19-1499; Rev 3; 12/08  
60mA, SOT23 Inverting Charge Pump  
with Shutdown  
General Description  
Features  
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  
12Ω 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.  
♦ 60mA Output Current  
♦ Low 12Ω Output Resistance  
♦ 150µA Supply Current (MAX1697R)  
♦ Requires Only Two 1µF Capacitors (MAX1697U)  
♦ Start-Up Current Limited  
♦ +1.25V to +5.5V Input Voltage Range  
♦ Slew-Rate Limited to Reduce EMI  
Ordering Information  
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.

Note 1: The MAX1697 requires special solder temperature pro-  
file described in the Absolute Maximum Ratings section.  
For applications with lower current requirements, the  
MAX1719/MAX1720/MAX1721 are pin-compatible  
SOT23 charge pumps that supply up to 25mA.  
Note 2: The MAX1697 is available with four different operating  
frequencies. Choose the desired frequency from the table  
below and insert the suffix in the blank above to complete the  
part number.

Note 3: MAX1697 is available in different package material.  
Add the following suffix to the part number when ordering:  
-T = Denotes a package containing lead(Pb).  
+T = Denotes a lead(Pb)-free/RoHS-compliant package.  
#T = Denotes an RoHS-compliant device that may include  
lead(Pb) that is exempt under the RoHS requirements.
