onsemi's CAT3647HV3-GT2 is a versatile 3-output DC-DC regulated LED driver IC. This device utilizes a switched capacitor (charge pump) topology to achieve efficient voltage conversion for driving multiple LED strings. With multi-step dimming capabilities and an integrated switch, the CAT3647HV3-GT2 offers precise control over LED brightness. This component is designed for applications requiring a compact and efficient LED backlight solution, such as in portable electronics and general lighting. It operates within a supply voltage range of 2.5V to 5.5V and provides an output current of 30mA per channel. The IC features a switching frequency between 1MHz and 1.3MHz, contributing to its small form factor and reduced filtering requirements. The CAT3647HV3-GT2 is supplied in a 16-TQFN (3x3) package, suitable for surface mount assembly.
