PAM2320
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 RDS(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.
