LD7241 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).
