ON Semiconductor FAN2315

15 A Integrated Synchronous Buck Regulator

Overview

Topology Buck Converter
Input voltage 4.5-15 V
Switching frequency 200-1000 kHz
Output 1 5.5 V / 15 A
IC revision 1.14

Description

The FAN2315 TinyBuck™ is a highly efficient integrated synchronous buck regulator. The regulator is capable of operating with an input range from 4.5 V to 15 V and supporting up to 15 A load currents.

The FAN2315 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. A hysteresis feature restarts the device when normal operating temperature is reached.
