Additional Infomation About Product

MCP1640/B/C/D 0.65V Start-Up Synchronous Boost Regulator with True Output Disconnect or Input/Output Bypass Option Features General Description Up to 96% Typical Efficiency The MCP1640/B/C/D is a compact, high-efficiency, fixed frequency, synchronous step-up DC-DC con- 800 mA Typical Peak Input Current Limit: verter. It provides an easy-to-use power supply solution -I > 100 mA 1.2V V , 3.3V V OUT IN OUT for applications powered by either single-cell, two-cell, -I > 350 mA 2.4V V , 3.3V V OUT IN OUT or three-cell alkaline, NiCd, NiMH, and single-cell Li-Ion -I > 350 mA 3.3V V , 5.0V V OUT IN OUT or Li-Polymer batteries. Low Start-Up Voltage: 0.65V, typical 3.3V V OUT Low-voltage technology allows the regulator to start-up 1 mA without high inrush current or output voltage overshoot Low Operating Input Voltage: 0.35V, typical from a low 0.65V input. High efficiency is accomplished 3.3V 1 mA OUT by integrating the low resistance N-Channel Boost Adjustable Output Voltage Range: 2.0V to 5.5V switch and synchronous P-Channel switch. All Maximum Input Voltage V < 5.5V compensation and protection circuitry is integrated to OUT minimize the number of external components. For Automatic PFM/PWM Operation (MCP1640/C): standby applications, the MCP1640 consumes only - PFM Operation Disabled (MCP1640B/D) 19 A while operating at no load, and provides a true - PWM Operation: 500 kHz disconnect from input to output while in Shutdown Low Device Quiescent Current: 19 A, typical (EN = GND). Additional device options are available by PFM Mode (not switching) operating in PWM-Only mode and connecting input to Internal Synchronous Rectifier output while the device is in Shutdown. Internal Compensation The true load disconnect mode provides input-to-out- Inrush Current Limiting and Internal Soft Start put isolation while the device is disabled by removing the normal boost regulator diode path from input-to- Selectable, Logic Controlled Shutdown States: output. The Input-to-Output Bypass mode option con- - True Load Disconnect Option (MCP1640/B) nects the input to the output using the integrated low - Input to Output Bypass Option (MCP1640C/D) resistance P-Channel MOSFET, which provides a low Shutdown Current (All States): < 1 A bias voltage for circuits operating in Deep Sleep mode. Low Noise, Anti-Ringing Control Both options consume less than 1 A of input current. Overtemperature Protection Output voltage is set by a small external resistor Available Packages: divider.
