description  
OUT2  
OUT1  
The TL1454 is a dual-channel pulse-width-modu-  
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. 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  
TL1454 to be used in ground-sensing battery chargers as well as voltage converters.

The D package is available taped and reeled. Add the suffix R to the device name (e.g., TL1454CDR). The  
PW package is available only left-end taped and reeled (indicated by the LE suffix on the device type; e.g.,  
TL1454CPWLE).
