Part Description

The MCP1663 device is a compact, high-efficiency, fixed-frequency, non-synchronous step-up DC-DC converter which integrates a 36V, 400 mΩ NMOS switch. It provides a space-efficient high-voltage step-up power supply solution for applications powered by either two-cell or three-cell alkaline, Ultimate Lithium, NiCd, NiMH, one-cell Li-Ion or Li-Polymer batteries. The integrated switch is protected by the 1.8A cycle-by-cycle inductor peak current limit operation. There is an output overvoltage protection which turns off switching in case the feedback resistors are accidentally disconnected or the feedback pin is short-circuited to GND. Low-voltage technology allows the regulator to start-up without high inrush current or output voltage overshoot from a low-voltage input. The device features a UVLO which avoids start-up and operation with low inputs or discharged batteries for two cell-powered applications. For standby applications (EN = GND), the device stops switching, enters sleep mode and consumes 0.3 µA (typical) of input current. MCP1663 is easy to use and allows creating classic boost, SEPIC or flyback DC-DC converters within a small Printed Circuit Board (PCB) area. All compensation and protection circuitry is integrated to minimize the number of external components. Ceramic input and output capacitors are used.
