MCP1623/24

Low-Voltage Input Boost Regulator

for PIC^®Microcontrollers

Features:

General Description:

• Up to 96% Typical Efficiency

The MCP1623/24 is a compact, high-efficiency, fixed

frequency, synchronous step-up DC-DC converter. It

provides an easy-to-use power supply solution for PIC

microcontroller applications powered by either one-cell,

two-cell, or three-cell alkaline, NiCd, NiMH, one-cell

Li-Ion or Li-Polymer batteries.

• 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

• Low Start-up Voltage: 0.65V, typical 3.3V V_OUT

@ 1 mA

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. The MCP1623 device option is available that

operates in PWM-only mode.

• 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)

• 500 kHz PWM Frequency

• 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

• SOT-23-6 Package
