MCP1630/MCP1630V
High-Speed, Microcontroller-Adaptable,
Pulse Width Modulator
Features Description High-Speed PWM Operation (12 ns Current
Sense to Output Delay) Operating Temperature Range:
-40В°C to +125В°C Precise Peak Current Limit (В±5%) (MCP1630) Voltage Mode and Average Current Mode Control
(MCP1630V) CMOS Output Driver (drives MOSFET driver or
low-side N-channel MOSFET directly) External Oscillator Input
(from PICВ® Microcontroller (MCU) External Voltage Reference Input (for adjustable
voltage or current output application) Peak Current Mode Operation > 1 MHz Low Operating Current: 2.8 mA (typ.) Fast Output Rise and Fall Times: 5.9 ns and
6.2 ns Undervoltage Lockout (UVLO) Protection Output Short Circuit Protection Overtemperature Protection The MCP1630/V is a high-speed Pulse Width Modulator (PWM) used to develop intelligent power systems.
When used with a microcontroller unit (MCU), the
MCP1630/V will control the power system duty cycle to
provide output voltage or current regulation. The MCU
can be used to adjust output voltage or current, switching frequency, maximum duty cycle and other features
that make the power system more intelligent. Applications Intelligent Power Systems
