MAX1852-MAX1853: SC70 Inverting Charge Pumps with Shutdown Data Sheet (Rev. 0)11/16/2000217K
Features and Benefits
- 30mA Output Current
- Low 15Ω Output Resistance
- 68µA Supply Current (MAX1852)
- Requires Only Two 0.68µF Capacitors (MAX1853)
- +2.5V to +5.5V Input Voltage Range
- 0.1µA Logic-Controlled Shutdown
- Two Switching Frequencies
- 50kHz (MAX1852)
- 200kHz (MAX1853)
- Slew-Rate Limited to Reduce EMI
- Ultra-Small 6-Pin SC70 Package
The MAX1852/MAX1853 monolithic, CMOS charge-pump voltage inverters in the ultra-small SC70 package feature a low 15Ω output resistance, permitting loads up to 30mA with maximum efficiency. The MAX1852/MAX1853 are available with operating frequencies of 50kHz and 200kHz, respectively, allowing optimization of supply current or external component size. Small external components and micropower shutdown mode make these devices ideal for both battery-powered and board-level voltage conversion applications.
Oscillator control circuitry and four power-MOSFET switches are included on-chip. Applications include generating a negative supply from a +5V or +3.3V logic supply to power analog circuitry. Both versions come in a 6-pin SC70 package that is 40% smaller than a SOT23.
- Battery-Powered Applications
- GaAsFET Bias Supplies
- Handy-Terminals, PDAs
- Negative Supply from +5V or +3.3V Logic Supplies
- Small LCD Panels
