CAT4137  
PIN DESCRIPTION  
VIN is the supply input for the internal logic. The  
device is compatible with supply voltages down to  
2.2V and up to 5.5V. A small bypass ceramic  
capacitor of 1µF is recommended between the VIN  
and GND pins near the device. The under-voltage  
lockout (UVLO) circuitry will place the device into an  
idle mode (not switching) whenever the supply falls  
below 1.9V.  
SW pin is the drain terminal of the internal low  
resistance power switch. The inductor and the  
Schottky diode anode should be connected to the  
SW pin. Traces going to the SW pin should be as  
short as possible with minimum loop area. This pin  
contains over-voltage circuitry which becomes active  
above 24V. In the event of an “Open-Led” fault  
condition, the device will enter a low power mode  
and the SW pin will be clamped to approximately  
30V.  
¯¯¯¯¯  
SHDN is the shutdown logic input. When the pin  
voltage is taken below 0.4V, the device immediately  
enters shutdown mode, drawing nearly zero current.  
At voltages greater than 1.5V, the device becomes  
fully enabled and operational.  
FB feedback pin is regulated at 0.3V. A resistor  
connected between the FB pin and ground sets the  
LED current according to the formula:  
ILED = 0.3V/R1  
GND is the ground reference pin. This pin should be  
connected directly to the ground plane on the PCB.  
The lower LED cathode is connected to the FB pin.
