PAM2303

3A Low Noise Step-Down DC-DC Converter

Features

Description

The PAM2303 is

a 3A step-down DC-DC

n Output Current: Up to 3A

converter. It operates in two different modes:

PSM and PWM modes. At light load, it

automactically enters into the PSM mode to

improve efficiency. At heavy load, the constant-

frequency PWM control performs excellent

stability and transient response. No external

n Output Voltage: 0.6V to V_IN

n Input Voltage: 2.7 to 5.5V

n Efficiency up to 95%

n 42μA (Typ) No Load Quiescent Current

n Shutdown Current: <1μA

n 100% Duty Cycle Operation

n 1.5MHz Switching Frequency

n Analog Soft Start

compensation components are required.

The PAM2303 supports a range of input voltages

from 2.7V to 5.5V. The output voltage is

adjustable from 0.6V to the input voltage. The

PAM2303 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.

n Storage Equipment

n Video Cards

n DDR Power Supply

The PAM2303 delivers 3A maximum output

current while consuming only 42μA of no-load

quiescent current. Ultra-low RDS(ON) integrated

MOSFETs and 100% duty cycle operation make

the PAM2303 an ideal choice for high output

voltage, high current applications which require a

low dropout threshold.

The PAM2303 is available in SOP-8(EP),

DFN3X3-10, and QFN3X3-16 package.
