Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

FAN53528
3.0 A, 2.4 MHz, Digitally Programmable Buck Regulator
Description
The FAN53528 is a step-down switching voltage
Features
regulator that delivers a digitally programmable output
.
.
.
.
.
Fixed-Frequency Operation: 2.4 MHz
Best-in-Class Load Transient
from an input voltage supply of 2.5 V to 5.5 V. The
output voltage is programmed through an I2C interface
capable of operating up to 3.4 MHz.
Continuous Output Current Capability: 3.0 A
2.5 V to 5.5 V Input Voltage Range
Digitally Programmable Output Voltage:
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.
0.35 V to 1.14375 V in 6.25 mV Steps
.
.
.
.
.
.
.
Programmable Slew Rate for Voltage Transitions
I2C-Compatible Interface Up to 3.4 Mbps
PFM Mode for High Efficiency in Light-Load
Quiescent Current in PFM Mode: 50 µA (Typical)
Input Under-Voltage Lockout (UVLO)
At moderate and light loads, Pulse Frequency
Modulation (PFM) is used to operate in Power-Save
Mode with a typical quiescent current of 50 µA 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 µA, reducing power consumption.
PFM Mode can be disabled if fixed frequency is desired.
The FAN53528 is available in a 15-bump, 1.310 mm x
2.015 mm, 0.4 mm ball pitch WLCSP.
