MCP1630 and MCP1631 High-Speed
PWM Controllers
The MCP1630 and MCP1631 offer another method that can
be used to generate high speed PWM signals for high power
LED drivers. The MCP1630 is an 8-pin device that contains
the components needed to generate an analog PWM control
loop, including an error amplifier, comparator and a high
current output pin to drive a power transistor.
The MCP1630 is designed to be used with a MCU that
provides a reference clock source. The MCU controls the
PWM frequency and maximum duty cycle. The switching
frequency can be up to 1 MHz, depending on the application
requirements. The MCU can also control the reference input
for the error amplifier when dimming or soft start functions
are required. Multiple MCP1630 devices can be attached to
a MCU to support multiple power channels.
The MCP1630 can be used to solve advanced power supply
issues. When multiple MCP1630 devices are used, phase
offsets can be applied to each clock input to reduce bus
current ripple. For applications that are sensitive to EMI,
dithering can be applied to the clock signal to reduce
radiated energy at a given frequency.
The MCP1631 is a 20-pin device which, in addition to
the MCP1630 includes an internal 5V or 3.3V regulator,
shutdown control, overvoltage protection, oscillator disable
and 1x and 10x gain amplifiers.
