MAX1697-60mA, SOT23, Inverting Charge Pump with Shutdown
The MAX1697 ultra-small, monolithic, CMOS chargepump high-voltage inverter accepts input voltages ranging from +1.25 V to +5.5 V. The device has an ultra-low 12½ output resistance, allowing loads of up to 60mA with maximum efficiency. The MAX1697 is available in 12kHz, 35KHZ, 125KHZ, operating frequency or 250kHz, allowing optimization of supply current or external component size. Its small external component micropower shutdown mode makes the device ideal for battery powered and board level voltage conversion applications. Oscillator control circuit and 4 power MOSFET on-chip switches. Applications include: generating negative power, supplying analog circuits from +5 V or +3.3 V logic. All versions are available in a 6-pin SOT23 package and provide 60mA. For low current requirements, the MAX1719/MAX1720/MAX1721 are pin-compatible SOT23 packages that provide up to 25mA of charge pump.
