HV9911规格书详情
General Description
The HV9911 is a current mode control LED driver IC designed to control single switch PWM converters (buck, boost or buck-boost), 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 (in the case of buck and buck-boost converters, the high side output current can be sensed by using the HV7800).
Features
Switch mode controller for single switch drivers
o Buck
o Boost
