TCM829ECT713

MICROCHIP  TCM829ECT713  芯片, 电荷泵转换器, SOT23A-5

The is a CMOS switched capacitor charge-pump Voltage Converter inverts and doubles an input voltage which can range from 1.5 to 5.5V. Conversion efficiency is typically >95%. Switching frequency is 12kHz for the TCM828. External component requirement is only two capacitors 3.3 µF nominal for standard voltage inverter applications. With a few additional components, a positive doubler can also be built. All other circuitry including control, oscillator and power MOSFETs, are integrated on-chip.
