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.

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.

PAM2320 3A LOW NOISE STEP-DOWN DC-DC CONVERTER Description Pin Assignments 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.
