TL594CDR2G Description

Short technical summary and product information.

The TL594CDR2G is a fixed-frequency, pulse width modulation (PWM) control circuit manufactured by On Semiconductor. It is primarily designed for use in switchmode power supplies. This IC integrates complete PWM control circuitry, including an on-chip oscillator with master or slave operation, on-chip error amplifiers, and an on-chip 5.0 V reference with 1.5% accuracy.

 

Key electrical specifications include a wide operating supply voltage range of 7V to 40V, with a maximum collector output voltage of 42V. The uncommitted output transistors are rated to 500 mA source or sink current. The device operates at frequencies up to 300 kHz and offers features such as adjustable deadtime control and output control for push-pull or single-ended operation. It supports both step-down and step-up/step-down topologies, including buck and push-pull configurations.

 

The TL594CDR2G is available in a 16-SOIC package, suitable for surface mounting. It operates within an ambient temperature range of -40°C to 85°C. The device also includes undervoltage lockout protection. It is Pb-Free and Halogen Free, complying with RoHS standards.
