LM2574 Datasheet (ON Semiconductor) - Step-Down Switching Regulator

LM2574, Step-Down Switching Regulator

Regulator, Step-Down Switching, Adjustable Output Voltage, 0.5 A LM2574 The LM2574 series of regulators are monolithic integrated circuits ideally suited for easy and convenient design of a step down switching regulator (buck converter).

All circuits of this series are capable of driving a 0.5 A load with excellent line and load regulation.

These devices are available in fixed output voltages of 3.3 V, 5.0 V, 12 V, 15 V, and an adjustable output version.

These regulators were designed to

LM2574 Features

* include a guaranteed ±4% tolerance on output voltage within specified input voltages and output load conditions, and ±10% on the oscillator frequency (±2% over 0°C to +125°C). External shutdown is included, featuring 60 mA (typical) standby current. The output switch includes cycle
