MCP1630

High-Speed, Microcontroller-Adaptable,

Pulse Width Modulator

Features

Description

• High-Speed PWM Operation (12 ns Current

Sense to Output Delay)

The MCP1630 is a high-speed Pulse Width Modulator

(PWM) used to develop intelligent power systems.

When used with a microcontroller, the MCP1630 will

control the power system duty cycle to provide output

voltage or current regulation. The microcontroller can

be used to adjust output voltage or current, switching

frequency, maximum duty cycle and other features

making the power system more intelligent and

adaptable.

• Operating Temperature Range: -40°C to +125°C

• Precise Peak Current Limit (±5%)

• CMOS Output Driver (Drives MOSFET Driver or

Low-Side N-channel MOSFET Directly)

• External Oscillator Input (from PICmicro^®

Microcontroller)

• External Voltage Reference Input (for adjustable

voltage or current output application)

Typical applications include smart battery chargers,

intelligent power systems, brick DC/DC converters, AC

power-factor correction, multiple output power supplies,

multi-phase power supplies and more.

• Peak Current Mode Operation to 1 MHz

• Low Operating Current: 2.8 mA, typical

• Fast Output Rise and Fall Times (5.9 ns and

6.2 ns)

The MCP1630 inputs were developed to be easily

attached to the I/O of a microcontroller. The microcon-

troller supplies the oscillator and reference to the

MCP1630 to provide the most flexible and adaptable

power system. The power system switching frequency

and maximum duty cycle are set using the I/O of the

microcontroller. The reference input can be external, a

D/A converter output or as simple as an I/O output from

the microcontroller. This enables the power system to

adapt to many external signals and variables in order to

optimize performance and facilitate calibration.

• Undervoltage Lockout

• Output Short Circuit Protection

• Overtemperature Protection

Applications

• Intelligent Power Systems

• Smart Battery Charger Applications

• Multiple Output/Multiple Phase Converters

• Output Voltage Calibration

When operating in current mode, a precise limit is set on

the peak current. With the fast comparator speed (typi-

cally 12 ns), the MCP1630 is capable of providing a

tight limit on the maximum switch current over a wide

input voltage range when compared to other high-speed

PWM controllers.

• AC Power Factor Correction

• VID Capability (Programmed and calibrated by

PICmicro Microcontroller)

• Buck/Boost/Buck-Boost/SEPIC/Flyback/Isolated

Converters

• Parallel Power Supplies

Additional protection features include: undervoltage

lockout, overtemperature and overcurrent.
