PWM controller, 1-fold, 3.0 ... 5.5 V, 300kHz, MSOP-8

High-Speed, Low-Side PWM Controller

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, Cuk, 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.
