LD7241 11/24/2008 5-Channel DC-DC Converter with 1 Channel Shutter Driver REV :00 General Description The LD7241 includes 5-channel PWM DC/DC controller IC and a Shutter controller. It can operate at 1MHz frequency and built in ON/OFF control, soft-start, power on/off sequence and output overload protection. Four channels have been integrated with MOSFETs and can achieve higher efficiency up to 90%~95% (CH1, CH2, CH3 and CH4). CH5 is a current source, ideally for 1WLED driver application. The LD7241 is also built with constant-current shutter driver. It optimizes overall efficiency and cost, and also reduces the board size. The LD7241 is available in a space-saving 5mm*5mm 40-pin QFN package. + Patented Features • 1.
