FAN53600 / FAN53610

3 MHz, 600 mA / 1A Synchronous Buck Regulator

Features

Description

The FAN53600/10 is a 3 MHz step-down switching voltage

regulator, available in 600 mA or 1 A options, that delivers a

fixed output from an input voltage supply of 2.3 V to 5.5 V.

600 mA or 1 A Output Current Capability

26 µA Typical Quiescent Current

3 MHz Fixed-Frequency Operation

Best-in-Class Load Transient Response

Best-in-Class Efficiency

Using

proprietary architecture with synchronous

rectification, the FAN53600/10 is capable of delivering a

peak efficiency of 92%, while maintaining efficiency over

80% at load currents as low as 1 mA.

The regulator operates at a nominal fixed frequency of

3 MHz, which reduces the value of the external components

to as low as 1 µH for the output inductor and 4.7 µF for the

output capacitor. In addition, the Pulse-Width Modulation

(PWM) modulator can be synchronized to an external

frequency source.

2.3 V to 5.5 V Input Voltage Range

0.8 V to 3.3 V Fixed Output Voltage

Low Ripple Light-Load PFM Mode

Forced PWM and External Clock Synchronization

Internal Soft-Start

At moderate and light loads, Pulse Frequency Modulation

(PFM) is used to operate the device in Power-Save Mode

with a typical quiescent current of 26 µA. Even with such a

low quiescent current, the part exhibits excellent transient

response during large load swings. At higher loads, the

system automatically switches to fixed-frequency control,

operating at 3 MHz. In Shutdown Mode, the supply current

drops below 1 µA, reducing power consumption. For

applications that require minimum ripple or fixed frequency,

PFM Mode can be disabled using the MODE pin.

Input Under-Voltage Lockout (UVLO)

Thermal Shutdown and Overload Protection

Optional Output Discharge

6-Bump WLCSP, 0.4 mm Pitch

Applications

3G, 4G, WiFi^®, WiMAX™, and WiBro^®Data Cards

The FAN53600/10 is available in 6-bump, 0.4 mm pitch,

Wafer-Level Chip-Scale Package (WLCSP).
