Quick Detail:
Switched Capacitor Voltage Converters
Description:
The TCM828/829 are CMOS “charge-pump” voltage converters in ultra-small 5-Pin SOT-23A packages. They invert and/or double an input voltage which can range from +1.5V to +5.5V. Conversion efficiency is typically >95%.
Switching frequency is 12kHz for the TCM828 and 35kHz for the TCM829.
External component requirement is only two capacitors (3.3µF 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 50µA (TCM828) and 115µA (TCM829).
The TCM828 and TCM829 are available in a 5-Pin SOT-23A surface mount package.
Applications:
■ Charge Pump in 5-Pin SOT-23A Package
■ >95% Voltage Conversion Efficiency
■ Voltage Inversion and/or Doubling
■ Low 50µA (TCM828) Quiescent Current
■ Operates from +1.5V to +5.5V
■ Up to 25mA Output Current
■ Only Two External Capacitors Required
