General Description
The MCP1633 High Speed PWM Controller is a pulsewidth
modulator developed for standalone power
supply applications. The MCP1633 design is based on
the MCP1632 PWM Controller but includes specific
blocks for PWM LED dimming. It is suitable for use in
topologies requiring a low-side MOSFET, such as
Boost, Flyback, SEPIC, CUK, etc.
The MCP1633 uses Current Mode Control to provide
superior bandwidth and transient response, and also
cycle-by-cycle current limiting with adjustable peak
offset. The MCP1633 is also capable of operating in
Voltage Mode Control if required.
The switching frequency of the MCP1633 can be set by
an external resistor between 200 kHz and 2.2 MHz.
The MCP1633 reference voltage is adjustable by using
only one external resistor.
The MCP1633 integrates a current sense amplifier with
programmable gain using external resistors.
The MCP1633 can achieve high performance LED
dimming by “freezing” the compensation network and
load disconnect capability.
The MCP1633 integrates a high speed comparator with
a high performance error amplifier with a PWM latch to
perform the high speed analog Power Supply PWM
function.
Integrated Undervoltage Lockout, Overvoltage
protection and Overtemperature Protection make
designs using the MCP1633 robust over a range of
external conditions.
