The TL1454ACPWR is a dual-channel pulse-width-modulation (PWM) control circuit from Texas Instruments, primarily intended for low-power, high-frequency DC/DC converters. Its applications include LCD displays, backlight inverters, and notebook computers.
This controller features two complete PWM control circuits with outputs that drive MOSFETs directly. It supports a wide supply voltage range from 3.6V to 20V and operates with a low supply current of 3.5 mA typical. The oscillator frequency can be set from 50 kHz to 2 MHz, and it includes adjustable dead-time control from 0% to 100%.
The TL1454ACPWR is available in a 16-TSSOP surface mount package. 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, while channel 2 drives p-channel MOSFETs.
Key electrical characteristics include a maximum duty cycle of 100% and a nominal reference voltage of 1.26V. The operating temperature range is -20°C to 85°C.
