General Description
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).
