The TL1454 is a dual-channel pulse-width-modu- GND 7 OUT1 8 10 VCC 9 OUT2 lation (PWM) control circuit, primarily intended for low-power, dc/dc converters.
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.
