GENERAL DESCRIPTION  
The ADP2443 is synchronous step-down, dc-to-dc regulator  
with an integrated 98 mΩ, high-side power metal oxide semicon-  
ductor field effect transistor (MOSFET) and a 35 mΩ, synchronous  
rectifier MOSFET to provide a high efficiency solution in a  
compact 4 mm × 4 mm LFCSP package. The regulators operate  
from an input voltage range of 4.5 V to 36 V. The output voltage  
can be adjusted down to 0.6 V and deliver up to 3 A of  
continuous current. The fast 50 ns minimum on time allows the  
regulators convert high input voltage to low output voltage at high  
frequency.  
Other key features include undervoltage lockout (UVLO),  
overvoltage protection (OVP), overcurrent protection (OCP),  
short-circuit protection (SCP), and thermal shutdown (TSD).  
The ADP2443 operates over the −40°C to +125°C operating  
junction temperature range and is available in a 24-lead, 4 mm ×  
4 mm LFCSP package.

The ADP2443 uses an emulated current mode, constant frequency  
pulse-width modulation (PWM) control scheme for excellent  
stability and transient response. The switching frequency of the  
ADP2443 can be programmed from 200 kHz to 1.8 MHz. The  
synchronization function allows the switching frequency be syn-  
chronized with an external clock to minimize the system noise.

The ADP2443 targets high performance applications that require  
high efficiency and design flexibility. External compensation  
and an adjustable soft start function provide design flexibility.  
The power-good output and precision enable input provide  
simple and reliable power sequencing.
