Diodes Incorporated’s 1.9W Class-D Audio Amplifier Delivers High SPL and Extends Battery Life

Diodes Incorporated introduced the PAM8905. Aimed at smartphones operating from a single-cell lithium-ion battery, the PAM8905 is a 1.9W class-D audio amplifier designed for audio systems that need to deliver a high sound pressure level (SPL) output from a low supply voltage. It achieves this with a built-in boost converter that generates the voltage rail for the output stage while using a battery-tracking automatic gain control (AGC) to adjust the gain and limit battery current when the battery voltage is low, thus prolonging battery life. With its high-efficiency class-D audio power amplifier and integrated boost converter, the PAM8905 drives up to 1.9W into an 8O speaker with a total harmonic distortion plus noise (THD+N) of just 1%. The fully synchronous topology of the boost circuit minimizes external components, achieves higher efficiency and maximizes the output power of the amplifier compared to a standard amplifier connected directly to the battery. The built-in AGC function ensures excellent sound reproduction and further helps extend battery lifetime. The PAM8905 features DC input voltage protection to prevent damage to the speaker in the event of input voltages with high DC bias levels. The device is also protected against output short circuits with full auto-recovery and has under-voltage lockout (UVLO) and over-temperature protection. Supplied in a 12-pin U-WLB1520-12 CSP package measuring just 15mm x 20mm x 0.6mm, the PAM8905 provides a low pin-count and small size solution to save board space.

Diodes Incorporated Introduces AP7344

Diodes Incorporated has introduced the AP7344. This dual 300mA low-dropout (LDO) regulator offers high 1% output accuracy and a low quiescent current of 50µA. The AP7344 features a small package to suit battery-powered consumer products such as cameras, smart phones and tablets. The AP7344 supports input voltages from 1.7V to 5.25V enabling it to cover the full range of Li+ batteries typically found in portable electronics systems. It provides a regulated output voltage, VOUT, that can be fixed between 1.2V and 3.6V, with an accuracy of 1% at +25oC, and is capable of driving 300mA loads. Other key performance features of this regulator include: low RDSON, a high PSRR of 75dB at 1kHz, low output noise of 60µVrms, and a low 50µA quiescent current that contributes to power savings, which lengthens battery life. The AP7344 comes in a small footprint X2-DFN1612-8 package, making it well-suited for the dense PCB layouts typical in portable electronics systems. It offers a competitive alternative to similar industry-standard LDOs with comparable performance but at a lower cost and with the added benefit of higher efficiency under light load operating conditions.

Diodes Incorporated Reports Unaudited Consolidated Earnings Results for the First Quarter Ended March 31, 2015; Provides Earnings Guidance for the Second Quarter of 2015

Diodes Incorporated reported unaudited consolidated earnings results for the first quarter ended March 31, 2015. For the quarter, the company reported net sales of $206,182,000 compared to $209,986,000 a year ago. Income from operations was $16,903,000 compared to $14,343,000 a year ago. Income before income taxes and non-controlling interest was $15,964,000 compared to $12,993,000 a year ago. Net income attributable to common stockholders was $11,132,000 or $0.23 per diluted share compared to $10,202,000 or $0.21 per diluted share a year ago. Adjusted net income was $12,729,000 or $0.26 per diluted share compared to $12,353,000 or $0.26 per diluted share a year ago. EBITDA was $35.3 million, compared to $32.8 million for the first quarter 2014 and $42.7 million for the fourth quarter 2014. Net cash provided by operating activities was $38.6 million. Free cash flow was $15.0 million, which includes $23.5 million of capital expenditures. For the second quarter of 2015, the company expects revenue to range between $212 million and $228 million, or an increase of 2.8% to 10.6% sequentially. The company expects gross margin to be 31.5%, plus or minus 2%. The company expects income tax rate to be 25%, plus or minus 3%.

Diodes Incorporated Introduces the AP22850

Diodes Incorporated has introduced the AP22850, a single-channel load switch designed to operate from 4.5V up to 12V with a near-zero quiescent supply current that reportedly makes it suitable for use in battery-powered netbooks, tablets and eReaders. The AP22850 can handle power up/down sequencing with load currents up to 8A and adjustable start-up and discharge rates. It is offered in the space-saving, thermally efficient 2mm x 2mm x 0.8mm W-DFN2020-8 package, maximizing available board space. The ever-increasing portable-computing market continues to demand more integrated and capable load switches. These are required for distributed power control and low-voltage differential signalling where switches rated for continuous output-current operation with power-good indication and adjustable discharge are key. These functions and performance are delivered cost-effectively by the AP22850, which is based on a P-channel MOSFET that has a low typical RDS(ON) of 20m. The device can handle inputs up to 12V with a maximum output current of 8A but with a quiescent (no-load) current of just 1.2nA. The AP22850 does not require an external gate pull-up resistor and integrates circuitry to suppress fast input transients from coupling to the output; these features contribute to reduced BOM costs and board area savings.

Diodes Incorporates Introduces the AP7342

Diodes Incorporated has introduced the AP7342. This low dropout regulator (LDO) delivers dual 150mA outputs with high 1% voltage accuracy from a wide 1.7V to 5.25V input voltage range. With a low 35µA quiescent current, low RDS(ON) and tiny 6-pin X2-DFN1212 package, this part is particularly well-suited for compact, low-power, handheld, consumer electronic products such as smart phones, tablets, cameras and portable media players. Additional benefits of the AP7342 are a high 75dB power supply rejection ratio (PSRR) and low 60µVrms noise sensitivity (from 10Hz to 100kHz). These are key to getting the best performance from audio and video applications or communications devices with RF sub-systems, such as wireless adaptors. A wide input voltage specification ensures compatibility with lithium batteries down to 1.7V, while the output voltage, which can be fixed between 1.2V and 3.6V, is maintained to 1% accuracy at +25oC and 1.5% across the full -40oC to +85oC operating temperature.
