General Description

The AAT3132/32A is a low noise, constant frequency charge pump DC/DC converter that uses fractional (1.5X) conversion to maximize efficiency for white LED applications.

The device can be used to produce current levels up to 20mA in three of its outputs and up to 25 or 30mA in one of its outputs to drive LEDs from a 2.7V to 5.5V input.

Outputs may be operated individually or paralleled for driving higher-current LEDs.

Key Features

  • ChargePump™ AnalogicTech's Simple Serial Control™ (S2Cwire™) interface is used to enable, disable, and set the LED drive current in two groups: the three 20mA outputs and the single 30mA output with multiple level logarithmic scales. The AAT3132/32A has a thermal management system to protect the device in the event of a short-circuit co.
