TI introduces the industry's smallest point-of-load DC/DC converters for harsh
High integration and small form factor reduce board space by up to 50 percent
DALLAS, Feb. 19, 2013
DALLAS, Feb. 19, 2013 /PRNewswire/ -- Texas Instruments Incorporated (TI)
(NASDAQ: TXN) today introduced the industry's smallest monolithic
point-of-load (POL) DC/DC converters for harsh environments, including
radiation tolerant, geological, heavy industrial, and oil and gas
applications. The 6.3-V, 6-A TPS50601 and the 6.3-V, 3-A TPS50301 are
synchronous step- down converters optimized for small form factor designs.
The devices' current mode control, high switching frequency, and integration
of the high- and low-side MOSFETs slash board space by 50 percent compared to
other solutions, reducing the size of equipment needed for tight spaces, such
as down-hole drilling. For more information or to order samples and an
evaluation module (EVM), see www.ti.com/tps50601-pr.
Key features and benefits of the TPS50601 and the TPS50301:
oPeak efficiency: Best-in-class peak efficiency of up to 95 percent results
in lower heat dissipation, compared to competitive devices.
oDesign flexibility: 100-kHz to 1-MHz switching frequency and optimized
compensation scheme enable designers to make trade-offs between size and
oReduced board space: High efficiency, optimal layout and dynamic bias
reduce the size and number of output capacitors, and improve transient
response. This enables more than 12-watts-per-square-inch power, compared
to the nearest competitor at 10 watts per square inch.
oHigh reliability: The TPS50301 is qualified up to +210 degrees-C for high
temperature applications, while the TPS50601 is qualified up to +125
degrees-Cfor harsh environments with QMLV/RHA qualifications pending.
oHigher-current operation: Designers can use two devices in parallel to
double the output current.
Packaging, availability and pricing
The TPS50601 and the TPS50301 are sampling now in a 20-pin thermally enhanced
dual in-line ceramic flatpack. Please contact email@example.com for
suggested retail price of the TPS50601, and firstname.lastname@example.org for
suggested retail price of the TPS50301.
Tools and support
The TPS50601 is supported by single- and dual-configured EVMs. The dual
TPS50601SPEVM-D provides high efficiency and high reliability due to reduced
stress on the components. The single TPS50601SPEVM-S implements split-input
power rails with separate voltage inputs for power stage and control
circuitry. Suggested retail price is US$499 for the single EVM and US$599 for
the dual EVM.
The harsh environment engineering model (EM), TPS50601HKHMPR, is a TPS50601
prototype for initial evaluation for harsh environment customers. The model
provides the same functionality and footprint as the TPS50601, but at a
reduced cost and for evaluation only.
A small form factor reference design of approximately 1 inch by 1 inch is
available. It features optimal layout, high efficiency, design calculations,
transient response, and information on the device design and test results.
The TPS50601 and the TPS50301 are supported by TI's WEBENCH^® Designer, an
online tool to simplify and speed the design process. SPICE models are also
available to simulate and debug the circuit.
Engineers can ask questions and get answers from TI experts on the High
Reliability Forum in the TI E2E™ Community.
