| The ultra-small MAX1682/MAX1683 monolithic, CMOS charge-pump voltage doublers accept input voltages ranging from +2.0V to +5.5V. Their high voltage-conversion efficiency (over 98%) and low operating current (110μA for MAX1682) make these devices ideal for both battery-powered and board-level voltage-doubler applications. Oscillator control circuitry and four power MOSFET switches are included on-chip. The MAX1682 operates at 12kHz, and the MAX1683 operates at 35kHz. A typical application includes generating a 6V supply to power an LCD display in a hand-held PDA. Both parts are available in a 5-pin SOT23 package and can deliver 30mA with a typical voltage drop of 600mV.5-Pin SOT23 Package +2.0V to +5.5V Input Voltage Range 98% Voltage-Conversion Efficiency 110μA Quiescent Current (MAX1682) Requires Only Two Capacitors Up to 45mA Output Current Applications Cell Phones Handy Terminals PDAs Small LCD Panels Meer informatie: | | Output Voltage: | 12V dc | Output Current: | 45mA | Input Voltage: | 2 → 5.5V dc | Mounting Type: | Surface Mount | Number of Outputs: | 1 | Efficiency: | 99.9 (Typ.)% | Maximum Temperature: | +85°C | Minimum Temperature: | -40°C | Application: | Cell Phones, Handy-Terminals, PDAs, Small LCD Panels | Depth: | 1.3mm | Length: | 3mm | Maximum Input Current: | 310µA | Special Features: | Requires Only Two Capacitors | Width: | 1.75mm |
