FAN2108 — TinyBuck™

3-24V Input, 8A, High-Efficiency, Integrated Synchronous

Buck Regulator

Features

Description

The FAN2108 TinyBuck™ is a highly efficient, small

footprint, 8A, synchronous buck regulator.

Wide Input Voltage Range: 3V-24V

Wide Output Voltage Range: 0.8V to 80% V_IN

8A Output Current

The FAN2108 contains both synchronous MOSFETs

and a controller/driver with optimized interconnects in

one package, which enables designers to solve high-

current requirements in a small area with minimal

external components.

Programmable Frequency Operation: 200KHz to

600KHz

Over 95% Peak Efficiency

External compensation, programmable switching

frequency, and current limit features allow design

optimization and flexibility.

Integrated Schottky Diode on Low-side MOSFET

Boosts Efficiency

Internal Bootstrap diode

The summing current mode modulator uses lossless

current sensing for current feedback and over-current

protection. Voltage feedforward helps operation over a

wide input voltage range.

Power-Good Signal

Pre-Bias Startup

Accepts Ceramic Capacitors on Output

External Compensation for Flexible Design

Input Under-Voltage Lockout

Programmable Current Limit

Fairchild’s advanced BiCMOS power process,

combined with low-R_DS(ON)internal MOSFETs and a

thermally efficient MLP package, provide the ability to

dissipate high power in a small package.

Under-Voltage, Over-Voltage, and Thermal

Shutdown Protections

Output over-voltage, under-voltage, and thermal

shutdown protections help protect the device from

damage during fault conditions. FAN2108 prevents pre-

biased output discharge during startup in point-of-load

applications.
