2A LOW NOISE STEP-DOWN DC-DC CONVERTER

Description

The PAM2310 is a 2A 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 PAM2310 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 PAM2310 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 PAM2310 delivers 2A 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 PAM2310 an

ideal choice for high output voltage, high current applications which

require a low dropout threshold.

The PAM2310 is available in SOP-8 package.
