AAT3152
High Efficiency 1X/1.
5X/2X Charge Pump for White LED Applications
General Description
The AAT3152 is a low noise, constant frequency charge pump DC/DC converter that uses a tri-mode load switch (1X), fractional (1.
5X), and doubling (2X) conversion to maximize efficiency for white LED applications.
The AAT3152 is capable of driving four-channel LEDs from a 2.
7V to 5.
5V input.
The current sinks may be operated individually or in parallel for driving higher-current LEDs.
A low external parts count (two 1µF flying capacitors and two small 1µF capacitors at VIN and VOUT) makes this part ideally suited for small, battery-powered applications.
