MCP1623/24

Low-Voltage Input Boost Regulator

for PIC^®Microcontrollers

Features

General Description

• Up to 96% Typical Efficiency

The MCP1623/24 is

fixed-frequency, synchronous

compact, high-efficiency,

step-up DC-DC

• 425 mA Typical Peak Input Current Limit:

- I_OUT> 50 mA @ 1.2V V_IN, 3.3V V_OUT

- I_OUT> 175 mA @ 2.4V V_IN, 3.3V V_OUT

- I_OUT> 175 mA @ 3.3V V_IN,5.0V V_OUT

converter. It provides an easy-to-use power supply

solution for PIC^®microcontroller applications powered

by either single-cell, two-cell, or three-cell alkaline,

NiCd, NiMH, and single-cell Li-Ion or Li-Polymer

batteries.

• Low Start-Up Voltage: 0.65V, 3.3V V_OUT@ 1 mA

(typical)

Low-voltage technology allows the regulator to start up

without high inrush current or output voltage overshoot

from a low 0.65V input. High efficiency is accomplished

by integrating the low-resistance N-Channel Boost

switch and synchronous P-Channel switch. All

compensation and protection circuitry are integrated to

minimize external components. For standby

applications, the MCP1624 operates and consumes

only 19 µA while operating at no load.

• Low Operating Input Voltage: 0.35V, typical

3.3V_OUT@ 1 mA

• Adjustable Output Voltage Range: 2.0V to 5.5V

• Maximum Input Voltage  V_OUT< 5.5V

• Automatic PFM/PWM Operation (MCP1624)

• PWM-Only Operation (MCP1623)

• PWM Operation: 500 kHz

• Low Device Quiescent Current: 19 µA, typical

PFM Mode

A “true” Load Disconnect mode provides input to output

isolation while disabled (EN = GND) by removing the

normal boost regulator diode path from input to output.

This mode consumes less than 1 µA of input current.

• Internal Synchronous Rectifier

• Internal Compensation

• Inrush Current Limiting and Internal Soft Start

• True Load Disconnect

Output voltage is set by a small external resistor

divider.

• Shutdown Current (All States): <1 µA

• Low Noise, Anti-Ringing Control

• Overtemperature Protection

• Available Packages:
