Description

The TC828A is a CMOS "charge-pump" voltage converter in an ultra-small 5-Pin SOT-23A package. TC828A can invert and/or double an input voltage that can range from +1.8V to +5.5V. Conversion efficiency is typically >95%, and switching frequency is 12KHz.The external component requirement is only two capacitors (10F nominal) for standard voltage inverter applications. With a few additional components a positive doubler can also be built. All other circuitry, including control, oscillator, power MOSFETs are integrated on-chip. Supply current is 38A typically.

The TC828A is available in a 5-Pin SOT-23A surface mount package.
