MCP1631/HV/MCP1631V/VHV is a high-speed analog pulse width modulator (PWM) that is suitable for designing programmable switch-mode battery chargers. It features high-speed operation frequency, peak current mode control, voltage mode control, and high-voltage options. In addition, it also has stable voltage output options, external oscillator input, external reference voltage input, integrated error amplifier, etc. It is suitable for applications such as high-input voltage programmable switch-mode battery chargers, LED lighting applications, constant current SEPIC power supply design, and USB input programmable switch-mode battery chargers.
The document details the MCP1631/HV, MCP1631V, and MCP1631VHV devices, which are high-speed analog pulse width modulators (PWM) designed to work with microcontrollers. These controllers offer peak current mode control for the standard series and voltage mode control for the 'V' variants, supporting various battery types including Li-ion, NiMH, NiCd, and lead-acid.
