Regulators Enable Use of PIC Microcontrollers with a Single Battery Cell

CHANDLER, Ariz.--(BUSINESS WIRE)-- Microchip Technology Inc. (NASDAQ: MCHP), a leading provider of microcontroller, analog, and Flash-IP solutions, today announced the MCP1623 and MCP1624 (MCP1623/4) Synchronous Boost Regulators, which bring low-voltage support to any PIC(R) microcontroller, providing a customizable solution for single-cell battery applications. Featuring a start-up voltage of 0.65V and an operating voltage down to 0.35V, the MCP1623/4 regulators reduce the number of batteries needed in a typical design even enabling designs to be powered from a single Alkaline, NiMh, NiCd, or disposable Lithium battery cell.

The MCP1623/4 Synchronous Boost Regulators extend battery life with up to 96% typical efficiency, shutdown current of less than one micro Ampere in all states and a true load-disconnect shutdown. The devices have an operating input voltage of 0.35 to 5.5V and an adjustable output voltage range of 2.0 to 5.5V. In reducing the number of batteries required, the MCP1623/4 regulators enable more environmentally friendly designs, with lower shipping and operating costs. The devices include over-temperature protection and provide 500 kHz PWM operation, enabling the use of smaller coils, with the MCP1624 providing automatic PWM/PFM switching.

"As customers continue to strive to create smaller, lighter, more compact designs, the ability to operate from a single battery is increasingly valuable," said Steve Drehobl, vice president of Microchip's Security, Microcontroller and Technology Development Division. "The MCP1623/4 regulators enable designers to reduce the size and number of batteries without increasing costs. These regulators can be utilized with any PIC microcontroller for < 0.7V VDD operation, which dramatically increases system flexibility."
