FAN53528

3.0 A, 2.4 MHz, Digitally

Programmable Buck

Regulator

Descriptions

www.onsemi.com

The FAN53528 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 rectification, the

FAN53528 is capable of delivering 3.0 A continuous at over 80%

efficiency, maintaining that efficiency at load currents as low as

10 mA. The regulator operates at a nominal fixed frequency of

2.4 MHz, which reduces the value of the external components.

Additional output capacitance can be added to improve regulation

during load transients without affecting stability.

At moderate and light−loads, Pulse Frequency Modulation (PFM) is

used to operate in Power−Save Mode with a typical quiescent current

of 50 mA at room temperature. 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 fixed frequency is desired. The

FAN53528 is available in a 15−bump, 1.310 mm × 2.015 mm, 0.4 mm

ball pitch WLCSP.
