ADP1111  
The circuit of Figure 27b may produce multiple pulses when  
approaching the trip point due to noise coupled into the SET  
input. To prevent multiple interrupts to the digital logic,  
hysteresis can be added to the circuit (Figure 27). Resistor  
RHYS, with a value of 1 MΩ to 10 MΩ, provides the hysteresis.  
The addition of RHYS will change the trip point slightly, so the  
new value for R1 will be:  
9 V to 5 V Step-Down Converter  
This circuit uses a 9 V battery to generate a +5 V output. The  
circuit will work down to 6.5 V, supplying 50 mA at this lower  
limit. Switch current is limited to around 500 mA by the 100 Ω  
resistor.

APPLICATION CIRCUITS  
All Surface Mount 3 V to 5 V Step-Up Converter  
This is the most basic application (along with the basic step-  
down configuration to follow) of the ADP1111. It takes full  
advantage of surface mount packaging for all the devices used in  
the design. The circuit can provide +5 V at 100 mA of output  
current and can be operated off of battery power for use in  
portable equipment.
