Beschreibung
The MCP1631/MCP1631V is a high-speed analog pulse width modulator (PWM) used to develop intelligent power systems. When combined with amicrocontroller, the MCP1631/MCP1631V will control the power system duty cycle providing output voltage or current regulation. The microcontroller can be used to adjust output voltage or current, switching frequencyand maximum duty cycle while providing additional features making the power system more intelligent, robust and adaptable.
Typical applications for the MCP1631/MCP1631V include programmable switch mode battery chargers capable of charging multiple chemistries, like Li-Ion, NiMH, NiCd and Pb-Acid configured as single or multiple cells. By combining with a small microcontroller, intelligent LED lighting designs andprogrammable SEPIC topology voltage and current sources can also be developed.
The MCP1631/MCP1631V inputs were developed to be attached to the I/O pins of a microcontroller for design flexibility. Additional features integrated into the MCP1631HV/MCP1631VHV provide signal conditioning and protection features for battery charger or constant current source applications.
For applications that operate from a high voltage input, the MCP1631HV and MCP1631VHV device options can be used to operate directly from a +3.5V to +16V input. For these applications, an additional low drop out+5V or +3.3V regulated output is available and can provide current up to 250 mA to power a microcontroller and auxiliary circuits.
