Product Details
The Microchip synchronous boost regulator are compact, high-efficiency, fixed-frequency, synchronous step-up DC-DC converters. This family of devices provides an easy-to-use power supply solution for applications powered by either one-cell, two-cell, or three-cell alkaline, Ultimate Lithium, NiCd, NiMH, one-cell Li-Ion or Li-Polymer batteries. Low-voltage technology allows the regulator to start-up without high inrush current or output voltage overshoot from a low voltage input. High efficiency is accomplished by integrating the low-resistance N-Channel Boost switch and synchronous P-Channel switch.
Up to 96% typical efficiency
Low start-up voltage 0.65 V, typical 3.3 V VOUT @ 1 mA
Low operating input voltage 0.35 V, typical 3.3 V VOUT @ 1 mA
Internal synchronous rectifier
Internal compensation
Inrush current limiting and internal soft-start
Shutdown current 1 μA
Over temperature protection
Low start-up voltage 0.65 V, typical 3.3 V VOUT @ 1 mA
Low operating input voltage 0.35 V, typical 3.3 V VOUT @ 1 mA
Internal synchronous rectifier
Internal compensation
Inrush current limiting and internal soft-start
