รายละเอียดสินค้า / Product Details

The HV9912 is a current mode control LED driver IC designed to control single switch PWM converters (buck, boost, buck-boost or SEPIC) in a constant frequency mode. The controller uses a peak current-mode 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 (in the case of buck and buck-boost converters, the output current can be sensed using a high side current sensor like the HV7800).
