Description:
The SR36015 regulator is an easy-to-use,synchronous, step-down DC/DC converter. With integrated high-side and low-side Power MOSFETs, up to 1.5A of output current can be delivered over a wide input voltage range from 4.2V to 60 V, with transient tolerance up to 66 V. The transient tolerance reduces the necessary design effort to protect against over-voltages and meets the surge immunity requirements of IEC 61000-4-5.
The SR36015 employs peak current-mode control to provide optimal efficiency and output voltage accuracy. Load transient performance is improved with FPWM feature in the 1-MHz regulator. Precision enable provides flexibility by supporting precise control over a direct connection to the wide input voltage or device start-up and shutdown. The power-good flag, with built-in filtering and delay, offers a true indication of system status, and negates the requirement for an external supervisor. The device requires few external components and has a pin-out designed for simple PCB layout. The small solution size and feature set of the SR36015 is designed to simplify implementation for a wide range of end equipment, including space critical applications of ultra-small field transmitters and vision sensors.
