Buck Switching Regulator IC - FAN23SV56AMPX Product Introduction
1. Overview
The FAN23SV56AMPX is a highly efficient integrated synchronous buck regulator designed by onsemi (formerly Fairchild Semiconductor). It is capable of operating with an input voltage range from 7V to 24V and supports a continuous load current of up to 6A. This regulator is ideal for applications requiring high efficiency and robust power management solutions.
2. Features
The FAN23SV56AMPX features a constant on-time control architecture that provides excellent transient response and maintains a relatively constant switching frequency. It includes pulse frequency modulation (PFM) mode for maximizing light-load efficiency by reducing the switching frequency when the inductor operates in discontinuous conduction mode (DCM), while keeping the minimum frequency above the audible range with ultrasonic mode. The regulator also offers a wide range of protection features, including output over-voltage, under-voltage, over-current, and thermal shutdown protections, which help prevent device damage during fault conditions. Additionally, it supports programmable switching frequency and over-current protection, providing flexible solutions for various applications.
3. Specifications
- Input Voltage Range: 7V to 24V using the internal linear regulator; 4.5V to 5.5V when VIN, PVIN, and PVCC are connected to bypass the internal regulator.
- Output Voltage Range: 0.6V to 5.5V.
- Continuous Output current: 6A.
- Switching Frequency: Programmable from 200kHz to 1.5MHz.
- Efficiency: Over 96% peak efficiency.
- Package: 34-Pin PQFN-EP (5x5.5mm), surface-mount compatible.
4. Applications
The FAN23SV56AMPX is suitable for a variety of applications, including mainstream notebooks, servers, desktop computers, game consoles, telecommunications, storage, and base stations. Its high efficiency and robust protection features make it an ideal choice for demanding power management requirements in these fields.
