lation (PWM) control circuit, primarily intended for
low-power, dc/dc co.
Applications
* include
LCD displays, backlight inverters, notebook com-
puters, and other products requiring small, high-frequency, dc/dc converters. Each PWM channel has its own
error amplifier, PWM comparator, dead-time control comparator, and MOSFET driver. The voltage reference,
oscillator, undervoltage lo
