3A LOW NOISE STEP-DOWN DC-DC CONVERTER

Description

The PAM2320 is a 3A step-down DC-DC converter. At heavy load,

the constant-frequency PWM control performs excellent stability and

transient response. No external compensation components are

required.

The PAM2320 supports a range of input voltages from 2.7V to 5.5V,

allowing the use of a single Li+/Li-polymer cell, multiple Alkaline/NiMH

cell, and other standard power sources. The output voltage is

adjustable from 0.6V to the input voltage. The PAM2320 employs

internal power switch and synchronous rectifier to minimize external

part count and realize high efficiency. During shutdown, the input is

disconnected from the output and the shutdown current is less than

1µA. Other key features include over-temperature and short circuit

protection, and under-voltage lockout to prevent deep battery

discharge.

The PAM2320 delivers 3A maximum output current while consuming

only 42µA of no-load quiescent current. Ultra-low R

DS(ON)

integrated

MOSFETs and 100% duty cycle operation make the PAM2320 an

ideal choice for high output voltage, high current applications which

require a low dropout threshold.

The PAM2320 is available in PSOP8 package.
