MCP1631/HV/MCP1631V/VHV

High-Speed, Pulse Width Modulator

Features

General Description

• Programmable Switching Battery Charger

Designs

The MCP1631/MCP1631V is a high-speed

analog pulse width modulator (PWM) used to develop

intelligent power systems. When combined with a

microcontroller, the MCP1631/MCP1631V will control

the power system duty cycle providing output voltage

or current regulation. The microcontroller can be used

to adjust output voltage or current, switching frequency

and maximum duty cycle while providing additional

features making the power system more intelligent,

robust and adaptable.

• High-Speed Analog PWM Controller

(2 MHz Operation)

• Combine with Microcontroller for “Intelligent”

Power System Development

• Peak Current Mode Control (MCP1631)

• Voltage Mode Control (MCP1631V)

• High Voltage Options Operate to +16V Input:

- MCP1631HV Current Mode

Typical applications for the MCP1631/MCP1631V

include programmable switch mode battery chargers

capable of charging multiple chemistries, like Li-Ion,

NiMH, NiCd and Pb-Acid configured as single or

multiple cells. By combining with a small

microcontroller, intelligent LED lighting designs and

programmable SEPIC topology voltage and current

sources can also be developed.

- MCP1631VHV Voltage Mode

• Regulated Output Voltage Options:

+5.0V or +3.3V

250 mA maximum current

• External Oscillator Input sets Switching

Frequency and Maximum Duty Cycle Limit

• External Reference Input Sets Regulation Voltage

or Current

The MCP1631/MCP1631V inputs were developed to

be attached to the I/O pins of a microcontroller for

design flexibility. Additional features integrated into the

MCP1631HV/MCP1631VHV provide signal condition-

ing and protection features for battery charger or

constant current source applications.

• Error Amplifier, Battery Current I_SNSAmplifier,

Battery Voltage V_SNSAmplifier Integrated

• Integrated Overvoltage Comparator

• Integrated High Current Low Side MOSFET

Driver (1A Peak)

For applications that operate from a high voltage input,

the MCP1631HV and MCP1631VHV device options

can be used to operate directly from a +3.5V to +16V

input. For these applications, an additional low drop out

+5V or +3.3V regulated output is available and can

provide current up to 250 mA to power a microcontroller

and auxiliary circuits.

• Shutdown mode reduces IQ to 2.4 µA (typical)

• Internal Overtemperature Protection

• Undervoltage Lockout (UVLO)

• Package Options:

- 4 mm x 4 mm 20-Lead QFN

(MCP1631/MCP1631V only)

- 20-Lead TSSOP (All Devices)

- 20-Lead SSOP (All Devices)

Applications

• High Input Voltage Programmable Switching

Battery Chargers

• Supports Multiple Chemistries Li-Ion, NiMH, NiCd

Intelligent and Pb-Acid

• LED Lighting Applications

• Constant Current SEPIC Power Train Design

• USB Input Programmable Switching Battery

Chargers
