New from Microchip is the MCP1631 2,0 MHz, high-speed pulse width modulator (PWM). The MCP1631 provides a means to close the feedback loop in switch-mode power supplies (SMPSs) that use microcontrollers for general system intelligence and control. The integration of the SMPS input and output interfaces in the MCP1631, via its high-speed voltage comparator, battery-voltage and current-sense amplifiers, and its 1 A MOSFET driver, enable designers to use this single device to perform many different functions in their designs. The device also includes protection features, such as under-voltage lockout and over-temperature protection. Designs based on the MCP1631 are capable of charging multiple battery chemistries, including Li-Ion, NiMH, NiCd and Lead Acid. A high-voltage version of the MCP1631 is available, which includes a linear regulator (LDO) that supports input voltages from 6 V to 16 V. The standard version of the device does not include the LDO, and operates directly from 3 V to 5,5 V.
