CAT37  
Operation  
The CAT37 device is a high efficiency, constant  
frequency, current regulating boost driver for white LEDs.  
The device includes a switch and an internally  
compensated loop for the regulation of the current in the  
LEDs.  
Operation can be best understood by examining the block  
diagram. The FB pin is regulated at 95 mV and the current  
through the external resistor will set the regulated current in  
the LEDs at:  
While maintaining LED current regulation, the CAT37  
boost converter automatically adjusts the FB pin voltage to  
be as low as possible. A low FB pin voltage ensures high  
efficiency.  
Current through the internal power switch is continuously  
monitored cyclebycycle. If the current limit is exceeded,  
the switch is immediately turned off, protecting the device,  
for the remainder of the cycle.  
PWM dimming operation can be achieved by switching  
the SHDN pin or by pulling the FB pin higher than 95 mV.
