ML4865 High Voltage High Current Boost Regulator

ML4865 Description

July 2000 ML4865 High Voltage High Current Boost Regulator GENERAL .
The ML4865 is a high voltage, continuous conduction boost regulator designed for DC to DC conversion in multiple cell battery powered systems.

ML4865 Features

* s Guaranteed full load start-up and operation at 1.8V input s Continuous conduction mode for high output current s Very low quiescent current s Pulse frequency modulation and internal synchronous rectification for high efficiency s Maximum switching frequency > 200kHz s Minimum external components s

ML4865 Applications

* using the internal synchronous rectifier: IOUT( MAX) V @ IN ´ 0.05 ´ VIN + 0.4 ´ 0.65 VOUT 70 VIN = 2V 21 6 7 60 with Schottky without Schottky 50 1 10 IOUT (mA) 100 1000 IIN = 0.05 ´ VIN + 0.4 h = 0.65 And for applications using an external Schottky: IOUT( MAX) @ VIN ™ 0.07 ™ VIN + 0.4 ™ 0.
