Description:
The MCP1632 high-speed PWM controller is a
pulse-width modulator developed for stand-alone power
supply applications. The MCP1632 includes a
high-speed analog control loop, a logic-level MOSFET
driver, an internal oscillator, a reference voltage
generator, and internal slope compensation. This high
level of integration makes it an ideal solution for
standalone SMPS applications. MCP1632 is suitable for
use in topologies requiring a low-side MOSFET control,
such as Boost, Flyback, SEPIC, Ćuk, etc. Typical
applications include battery chargers, intelligent power
systems, brick DC-DC converters, LED drivers. Due to
its low power consumption, the MCP1632 PWM
controller is recommended for battery-operated
applications.
The MCP1632 offers a Peak Current mode control in
order to achieve consistent performance regardless of
the topology of the power train or the operating
conditions. In addition, the MCP1632 can implement
the Voltage Mode Control for cost-sensitive solutions.
The MCP1632 PWM controller can be easily interfaced
with PIC microcontrollers in order to develop an
intelligent power solution.
Additional features include: UVLO, overtemperature
and overcurrent protection, shutdown capability (EN
pin) and an adjustable soft start option.
