AAT3151B
High Efficiency 1X/1.
5X Charge Pump For White LED Applications
General Description
The AAT3151B is a low noise, constant frequency charge pump DC/DC converter that uses a dual mode load switch (1X) and fractional (1.
5X) charge pump conversion to maximize efficiency for white LED applications.
The AAT3151B is capable of driving four white LEDs at a total of 120mA 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 the AAT3151B ideally suited for small battery-powered applications.
