Detalii tehnice
Prezentare generală a produsului
The MCP16251T-I/CH is a compact high-efficiency fixed frequency synchronous step-up DC-DC Converter provides an easy-to-use power supply solution for applications powered by either one-cell, two-cell or three-cell alkaline, NiCd, NiMH, one-cell Li-ion or Li-polymer batteries. A 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. All compensation and protection circuitry are integrated to minimize external components. MCP16251 operates and consumes less than 14µA from battery, while operating at no load (VOUT = 3.3V, VIN = 1.5V). The devices provide a true disconnect from input to output (MCP16251) or an input-to-output bypass (MCP16252), while in shutdown (EN = GND). Both options consume less than 0.6µA from battery.
