General Description
The MAX1697 ultra-small, monolithic, CMOS charge-
pump voltage inverter accepts an input voltage ranging
from +1.25V to +5.5V. This device features an ultra-low
12
output resistance, permitting loads of up to 60mA
with maximum efficiency. The MAX1697 is available
with operating frequencies of 12kHz, 35kHz, 125kHz, or
250kHz, allowing optimization of supply current or
external component size. Its small external components
and micropower shutdown mode make this device
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. All versions come in a
6-pin SOT23 package and deliver 60mA.
For applications with lower current requirements, the
MAX1719/MAX1720/MAX1721 are pin-compatible
SOT23 charge pumps that supply up to 25mA.
Applications
Negative Supply from +5V or +3.3V Logic Supplies
