FAN53555

5 A, 2.4 MHz, Digitally

Programmable TinyBuck^®

Regulator

Description

www.onsemi.com

The FAN53555 is a step−down switching voltage regulator that

delivers a digitally programmable output from an input voltage supply

of 2.5 V to 5.5 V. The output voltage is programmed through an I C

interface capable of operating up to 3.4 MHz.

Using a proprietary architecture with synchronous

• 2.5 V to 5.5 V Input Voltage Range

rectification, the FAN53555 is capable of delivering 5 A

continuous at over 80% efficiency, while maintaining over

80% efficiency at load currents as low as 10 mA. Pulse

currents as high as 6.5 A can be supported by the 05 option.

The regulator operates at a nominal fixed frequency of

2.4 MHz, which reduces the value of the external

components to 330 nH for the output induction and as low

as 20 mF for the output capacitor. Additional output

capacitance can be added to improve regulation during load

transients without affecting stability. Inductance up to

1.2 mH may be used with additional output capacitance.

At moderate and light loads, Pulse Frequency Modulation

(PFM) is used to operate in Power−Save Mode with a typical

quiescent current of 60 mA. 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 2.4 MHz.

In Shutdown Mode, the supply current drops below 1 mA,

reducing power consumption. PFM Mode can be disabled if

constant frequency is desired. The FAN53555 is available in

a 20−bump, 1.6 x 2 mm, WLCSP.
