Supertex Continues Support for MEMS and Other High Voltage Markets With Release of a New High Voltage Non-Isolated Power Controller HV9150 Hysteretic Boost Controller for Battery Level Inputs SUNNYVALE, CA -- (Marketwired) -- 12/03/13 -- Supertex (NASDAQ: SUPX), a recognized leader in high voltage analog and mixed signal integrated circuits (ICs), expanded its product offerings in support of MEMS and other high voltage solutions with the introduction of the HV9150. The HV9150 is a power management IC, a hysteretic controller that is intended to simply and easily provide a non-isolated, regulated high voltage output (6V to 500V) from a battery level input (2.7V to 4.5V). In today's world of improved battery technology and equipment portability, portable instrumentation and other industrial applications requiring high voltage often requires complex, high component count circuitry to create the necessary high voltage bias supplies. As part of its ongoing commitment to the high voltage market, the HV9150 was created to simplify high voltage regulation for these applications, in supplement to its strategy of developing next generation solutions for optical switching applications, as well as other high voltage applications. The HV9150 is designed as a versatile, simple hysteretic controller, working at a fixed, user set frequency (40kHz to 400kHz) and duty cycle (50% to 87.5%, 4 options). This 'burst-mode' or hysteretic controller is very simple in operation, with regulation achieved through a valve-control approach, where the pulse chain is gated for drive of the main power switch in response to a droop in output voltage. Given its hysteretic nature, the controller is naturally stable, with no feedback compensation requirements to consider. Designed to work with an external MOSFET, the HV9150 is designed to support power levels of up to 5W. The gate voltage for the off-board MOSFET can be generated from a lower voltage with an on board charge pump, or from a higher off board voltage through an on board linear regulator. Other features include a ground switch in the feedback path for power savings when the chip is in the low power state and provision for an external reference voltage. "Supertex is a strong supplier of solutions in this space, and the Company is rapidly working to expand its relationships with other key suppliers and customers in this market," states Jimes Lei, Director of Application Engineering of Supertex. "Supertex will continue to improve its unique process capabilities, and provide increasing levels of service and value to its expanding base of MEMS customers." The HV9150 is available in a lead(Pb)-free/RoHS compliant 16-lead 3x3 QFN package (HV9150K6-G). Samples and demoboard (HV9150DB1) are available from stock. Lead-time for production quantities is 4-6 weeks, ARO. Pricing is US$0.77 each in 1K quantities.
