1.2A White LED Regulating Charge Pump for  
Camera Flashes and Movie Lights  
General Description  
Features  
The MAX1577Y/MAX1577Z charge pumps drive white  
LEDs, including camera strobes, with regulated current  
up to 1.2A (guaranteed to 800mA). The very low open-  
loop output resistance allows high flash brightness,  
even from a low battery input voltage. The adaptive  
1x/2x regulating charge-pump operation provides high  
efficiency (up to 92%) while in movie mode or back-  
lighting. Fast (1MHz) switching allows the use of tiny  
external components.  
♦ Up to 1.2A Output Drive Capability (800mA  
Guaranteed)

♦ Flexible Brightness Control  
Two-Bit Logic for 100%, 33%, 20%, and Off  
PWM for 20% to 100%  
♦ 3% Current Regulation Over Line and  
Temperature  
♦ Current or Voltage Regulation for Flash and  
Backlighting (MAX1577Y)  
♦ Current Regulation for Flash (MAX1577Z)  
The MAX1577Y/MAX1577Z use an external resistor to  
set the full-scale LED current. Two enable inputs (EN1  
and EN2) provide simple on/off control and LED current  
of 20%, 33%, or 100% full scale. If there is less than  
24mV across the external resistor, the output voltage is  
regulated. The MAX1577Z has fixed 5.1V output-volt-  
age regulation, while the MAX1577Y has logic-con-  
trolled output voltage of 3.4V, 4.6V, or 5.1V for  
backlighting, keyboard, and RGB applications.  
♦ Low Ripple and EMI  
♦ 2.7V to 5.5V Supply Voltage Range  
♦ Soft-Start Limits Inrush Current  
♦ Output-Voltage Regulation Mode  
♦ Thermal-Shutdown Protection  
♦ 8-Pin 3mm x 3mm TDFN Package  
The MAX1577Y/MAX1577Z are available in an 8-pin,  
3mm x 3mm TDFN package (0.8mm max height).
