| Description | 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, back... |
| Features |
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 b... |
