MAX1682-MAX1683: Switched-Capacitor Voltage Doublers Data Sheet (Rev. 3)12/15/2010PDF176K
Overview
Features and Benefits
- 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
Product Details
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.
Applications
- Cell Phones
- Handy Terminals
- PDAs
- Small LCD Panels
