SEM5025 datasheet

Description :

LCD Power Management IC Chip, LED Inverter, Protection

The SEM5025 is a current mode control LED driver IC designed to control single switch PWM converters (buck, boost, buckboost, or SEPIC), in a constant frequency or constant off-time mode. The controller uses a peak current control scheme, (with programmable slope compensation), and includes an internal transconductance amplifier to control the output current in closed loop, enabling high output current accuracy.
