description  
OUT2  
OUT1  
The TL1454A is a dual-channel pulse-width-mod-  
ulation (PWM) control circuit, primarily intended  
for low-power, dc/dc converters. Applications  
include LCD displays, backlight inverters, note-  
book computers, 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 lockout, and short-circuit protection are common to both  
channels.  
Channel 1 is configured to drive n-channel MOSFETs in step-up or flyback converters, and channel 2 is  
configured to drive p-channel MOSFETs in step-down or inverting converters. The operating frequency is set  
with an external resistor and an external capacitor, and dead time is continuously adjustable from 0 to 100%  
duty cycle with a resistive divider network. Soft start can be implemented by adding a capacitor to the dead-time  
control (DTC) network. The error-amplifier common-mode input range includes ground, which allows the  
TL1454A to be used in ground-sensing battery chargers as well as voltage converters.
