| Category | PMIC – Voltage Mode PWM Controllers |
| Description | Fixed Frequency PWM Controller, 40V Input, Dual Output, 300kHz Switching Frequency, SOIC-16 Package |
Product Overview
The TL494CDR is a versatile fixed-frequency pulse width modulation (PWM) controller designed for switched-mode power supply applications including buck, boost, push-pull, half-bridge, and full-bridge topologies. It integrates all essential functions required for a PWM control circuit, featuring a complete on-chip oscillator, error amplifier, dead-time control, pulse-steering flip-flop, and 5V precision reference voltage source. This device supports dual push-pull output configurations with adjustable duty cycle up to 97%, enabling efficient power regulation in a wide range of power conversion systems. With a wide input voltage range up to 40V and excellent temperature stability, the TL494CDR delivers reliable performance in industrial, consumer, and automotive power management designs, packaged in a compact SOIC-16 surface-mount form factor for high-density PCB integration.
