onsemi DC DC Switching Controllers TL494BD

The TL494BD is a pulse width modulation control circuit designed for switch-mode power supply applications. It features complete PWM control circuitry, an on-chip oscillator capable of master or slave operation, and integrated error amplifiers. The device includes a 5.0 V reference, adjustable deadtime control, and uncommitted output transistors rated for 500 mA source or sink current. It supports both push-pull and single-ended output configurations and incorporates undervoltage lockout functionality. The TL494BD operates with a power supply voltage range of 7.0 V to 40 V and can handle collector output voltages up to 42 V. It is available in a 16-pin SOIC package and is suitable for automotive applications under the NCV prefix, which indicates compliance with specific site and control changes. The device is also offered in Pb-free packaging options. With a wide operating temperature range of -40¬8C to +125¬8C, the TL494BD is suitable for various demanding environments.
