Description

The MCP16321/2 is a highly integrated, high-efficiency,

fixed frequency, synchronous step-down DC-DC

converter in a 16-pin QFN package that operates from

input voltages up to 24V. Integrated features include a

high-side and low-side N-Channel switch, fixed

frequency Peak Current Mode Control, internal

compensation, peak current limit, V

OUT

overvoltage

protection and overtemperature protection. Minimal

external components are necessary to develop a

complete synchronous step-down DC-DC converter

power supply.

High converter efficiency is achieved by integrating a

high-speed, current limited, low resistance, high-side

N-Channel MOSFET, as well as a high-speed, low

resistance, low-side N-Channel MOSFET and

associated drive circuitry. High switching frequency

minimizes the size of the inductor and output capacitor,

resulting in a small solution size.

The MCP16321/2 device can supply 1A/2A of

continuous current while regulating the output voltage

from 0.9V to 5V. A high-performance peak current

mode architecture keeps the output voltage tightly

regulated, even during input voltage steps and output

current transient conditions that are common in power

supplies.

The regulator can be turned on and off with a logic level

signal applied to the EN input. The EN input is internally

pulled up to a 4.2V reference and is rated for a

maximum of 6V. With EN low, typically 5 µA of current

is consumed from the input, making the part ideal for

power shedding and load distribution applications. The

PG output is an open-drain output pin used to interface

with other components of the system, and can be

pulled up to a maximum of 6V.

The output voltage can either be fixed at output

voltages of 0.9V, 1.5V, 1.8V, 2.5V, 3.3V, 5V or

adjustable using an external resistor divider. The

MCP16321/2 is offered in a 3x3 QFN-16 surface mount

package.
