What are some of the current Pulse Width Modulator ICs?
High-Speed, Pulse Width Modulator Microchip Technologys MCP1631 and MCP1631V are high-speed analog PWMs.. When combined with a microcontroller, the MCP1631/MCP1631V can control the power system duty cycle providing output voltage or current regulation. The microcontroller can be used to adjust output voltage or current, switching frequency and maximum duty cycle while providing additional features making the power system more intelligent, robust and adaptable. The MCP1631(current mode control) and MCP1631V (voltage mode control) contain the PWM, MOSFET driver, current sense amplifier, voltage sense amplifier, and overvoltage comparator. These ICs operate with a 3.0 V to 5.5V input. Additional features include shutdown, undervoltage lockout (UVLO), and overtemperature protection. For applications that operate from a high voltage input, the MCP1631HV and MCP1631VHV can operate directly from a +3.5V to +16V input. For these applications, an additional low drop out +5V or +3.3V regulated o
