Product Overview
LTC3240-3.3 is a step-up/step-down charge pump DC/DC converter. With input voltages greater than the regulated output voltage, the device operates as a low dropout regulator. Once the input voltage drops within 100mV of the regulated output voltage, the part automatically switches to step-up mode. In step-up mode the device operates as a constant frequency (1.2MHz) doubling charge pump. Built-in soft-start circuitry prevents excessive inrush current during start-up. Thermal shutdown and current-limit circuitry allow the parts to survive a continuous short-circuit from VOUT to GND. It require only three tiny external ceramic capacitors for an ultra small application footprint. It is widely used in application such as 2AA to 2.5V, 2-3 AA/Li-Ion to 3.3V, low power supplies for cameras, I/O supplies, audio, PC cards, Misc. logic, etc., in a wide variety of handheld products.
- VIN range is 1.8V to 5.5V
- Output current upto 150mA
- Automatic mode switching, efficiency is 87% typical at (VIN = 3.7V, IOUT = 100mA)
- Low dropout regulator operation in step-down mode
- Shutdown disconnects load from input
- No load input current is 65µA typical at (IOUT = 0, 1.8V <= VIN <= 5.5V)
- Shutdown current is 1µA maximum
- Output voltage range is 3.3V typical
- Operating temperature is -40°C to 85°C
- Package style is 6-lead plastic DFN
