ON Semiconductor FAN23SV10M

10 A Integrated Synchronous Buck Regulator

Overview

TopologyBuck Converter
Input voltage7-15 V
Switching frequency200-1500 kHz
Output 15.5 V / 10 A

Description

The FAN23SV10M TinyBuck™ is a highly efficient integrated synchronous buck regulator. The regulator is capable of operating with an input range from 7 V to 15 V and supporting up to 10 A load currents. The device can operate from a 5 V rail (±10%) if VIN, PVIN, and PVCC are connected together to bypass the internal linear regulator.

This FAN23SV10M utilizes Fairchild’s constant on-time control architecture to provide excellent transient response and to maintain a relatively constant switching frequency. The device utilizes Pulse Frequency Modulation (PFM) mode to maximize light-load efficiency by reducing switching frequency when the inductor is operating in discontinuous conduction mode at light loads.

Switching frequency and over-current protection can be programmed to provide a flexible solution for various applications. Output over-voltage, under-voltage, over-current, and thermal shutdown protections help prevent damage to the device during fault conditions. After thermal shutdown is activated, a hysteresis feature restarts the device when normal operating temperature is reached.
