Renesas Electronics, ISL85415FRZ Synchronous Buck Regulator, 1-Channel 500mA Adjustable 12-Pin, DFN-EP-12

The Renesas Electronics synchronous buck regulator synchronous buck regulator with an input range of 3V to 36V. The feature can be disabled if forced PWM mode is desired. By integrating both NMOS devices and providing internal configuration options, minimal external components are required, reducing both the BOM count and complexity of design.

Synchronous operation for high efficiency
No compensation required
Integrated high-side and low-side NMOS devices
Selectable PFM or forced PWM mode at light loads
