2A 150KHZ PWM Buck DC/DC Converter
HY1509
General Description
Features
The HY1509 is a of easy to use adjustable step-down (buck) switch-mode voltage regulator. The device is available in an adjustable output version. It is capable of driving a 2A load with excellent line and load regulation.
Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation, and a fixed-frequency oscillator.
The output voltage is guaranteed to ±3% tolerance under specified input voltage and output load conditions. The oscillator frequency is guaranteed to ±15%. External shutdown is included, featuring typically 50 µA standby current.
