KAC3301QN Datasheet 1x/1. 5x Fractional Charge Pump For White Led Driver

Manufacturer: KEC

Overview: SEMICONDUCTOR TECHNICAL DATA 1X/1. 5X Fractional Charge Pump for White LED Driver with Dimming Control KAC3301QN Analog CMOS Integrated Circuits .. E Pin 1 D 13 16 The KAC3301 is low noise constant frequency charge pump DC/DC converter specially designed to drive up to four white LEDs with constant current from Li-ion cell. Dual (1x/1.5x) Modes and low dropout voltage of LED driver maximize efficiency for the white LED application over full Li-ion battery input range. The LED current is set by the external resistor. PWM(Pulse Width Modulation) signal can be used to control LED brightness over wide frequency range. Various kinds of protection circuits protect your system from every undesirable output condition.
