CAT3612HV2-GT2

Overview

The CAT3612HV2-GT2 is a programmable camera flash LED driver IC manufactured by onsemi. It operates with an input voltage range of 3V to 5.5V and provides two output channels, each capable of delivering up to 150mA for flash applications. The device utilizes a switched capacitor (charge pump) topology to generate an output voltage of up to 7V. It supports multi-step dimming control and features an internal switch. The component is housed in a 12-TDFN (3x3) surface-mount package with an exposed pad and is rated for operation between -40°C and +85°C ambient temperature.
