MCP1663
High-Voltage Integrated Switch PWM Boost Regulator with UVLO
Features General 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. 36V, 400 mΩ Integrated Switch
