MAX1561／MAX1599 white LED driver circuit diagram

Published:2011/8/12 3:05:00 Author:Lucas | Keyword: white LED driver | From:SeekIC

MAX1561/MAX1599 contains high-voltage, low RDS-ON N-channel MOSFET switch, which provides high conversion efficiency and extends battery life. Dual-mode input provides a simple brightness adjustment and switching control. MAX1561's 1MHz (MAX1599 to 500kHz) high-speed, current-mode pulse-width modulation (PWM) architecture allows for small input and output capacitors and inductors, and to minimize the ripple on input power (battery). Programmable soft-start function can eliminate inrush current during startup.
