Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, today announced the MCP1640 Synchronous Boost Regulator, which features an operating voltage down to 0.35V, quiescent current as low as 19 microamperes, and shutdown current of less than one microampere.

The MCP1640 regulator’s operating voltage of down to 0.35V and start-up voltage of 0.65V allows use with even a single, completely drained Alkaline, NiMh or NiCd battery cell. A PWM/PFM option enables the device’s low quiescent and shutdown currents, and provides up to 96per cent efficiency; allowing for longer battery run times. The regulator’s two integrated FET transistors reduce component count, resulting in smaller overall designs.
“The MCP1640 addresses customer needs to reduce the number of batteries required for their applications, while providing long run times and compact design sizes,” said Bryan J. Liddiard, vice president of Microchip’s Analog and Interface Products Division.
Mikhail Voroniouk, senior product marketing engineer with Microchip’s Analog and Interface Products Division, added, “The MCP1640 Boost regulator continues Microchip’s leadership in low-power products, complementing our eXtreme Low Power PIC microcontrollers, especially in applications that must operate from a single-cell battery.”
