MCP1640/B/C/D

0.65V Start-up Synchronous Boost Regulator with True

Output Disconnect or Input/Output Bypass Option

Features

General Description

• Up to 96% Typical Efficiency

The MCP1640/B/C/D is a compact, high-efficiency,

fixed frequency, synchronous step-up DC-DC con-

verter. It provides an easy-to-use power supply solution

for applications powered by either one-cell, two-cell, or

three-cell alkaline, NiCd, NiMH, one-cell Li-Ion or

Li-Polymer batteries.

• 800 mA Typical Peak Input Current Limit:

- I_OUT> 100 mA @ 1.2V V_IN, 3.3V V_OUT

- I_OUT> 350 mA @ 2.4V V_IN, 3.3V V_OUT

- I_OUT> 350 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 MCP1640 operates and consumes

only 19 µA while operating at no load and provides a

true disconnect from input to output while shut down

(EN = GND). Additional device options are available

that operate in PWM only mode and connect input to

output bypass while shut down.

• 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 (MCP1640/C):

- PFM Operation Disabled (MCP1640B/D)

- PWM Operation: 500 kHz

• Low Device Quiescent Current: 19 µA, typical

PFM Mode

• Internal Synchronous Rectifier

• Internal Compensation

A “true” load disconnect mode provides input to output

isolation while disabled by removing the normal boost

regulator diode path from input to output. A bypass

mode option connects the input to the output using the

integrated low resistance P-Channel MOSFET, which

provides a low bias keep alive voltage for circuits

operating in Deep Sleep mode. Both options consume

less than 1 µA of input current.

• Inrush Current Limiting and Internal Soft-Start

• Selectable, Logic Controlled, Shutdown States:

- True Load Disconnect Option (MCP1640/B)

- Input to Output Bypass Option (MCP1640C/D)

• Shutdown Current (All States): < 1 µA

• Low Noise, Anti-Ringing Control

• Overtemperature Protection

Output voltage is set by a small external resistor

divider. Two package options, SOT23-6 and 2x3

DFN-8, are available.

• Available Packages:

- SOT23-6

- 2x3 8-Lead DFN
