ML4865  
High Voltage High Current Boost Regulator  
Features  
General Description  
• Guaranteed full load start-up and operation at 1.8V input  
• Continuous conduction mode for high output current  
Very low quiescent current  
• Pulse frequency modulation and internal synchronous  
rectification for high efficiency  
• Maximum switching frequency > 200kHz  
• Minimum external components  
• Low ON resistance internal switching FETs  
• Fixed 12V output can be adjusted to lower output voltages  
The ML4865 is a high voltage, continuous conduction boost  
regulator designed for DC to DC conversion in multiple cell  
battery powered systems. Continuous conduction allows the  
regulator to maximize output current for a given inductor.  
The maximum switching frequency can exceed 200kHz,  
allowing the use of small, low cost inductors. The ML4865 is  
capable of start-up with input voltages as low as 1.8V and  
generates a 12V output with output voltage accuracy of 4ꢀ.  
Unlike most boost regulators, the ML4865 isolates the load  
from the battery when the SHDN pin is high. An integrated  
synchronous rectifier eliminates the need for an external  
Schottky diode and provides a lower forward voltage drop,  
resulting in higher conversion efficiency. In addition, low  
quiescent battery current and variable frequency operation  
result in high efficiency even at light loads. The ML4865  
requires only one inductor and two capacitors to build a very  
small regulator circuit capable of achieving conversion effi-  
ciencies approaching 90ꢀ.
