ML4851 Datasheet | Micro Linear

FEATURING Extended mercial Temperature Range -20˚C to 70˚C for Portable Handheld Equipment ML4851- Low Current, Voltage Boost Regulator GENERAL DESCRIPTION The ML4851 is a low power boost regulator designed for DC to DC conversion in 1 to 3 cell battery powered systems. The maximum switching frequency can exceed 100kHz, allowing the use of small, low cost inductors. The bination of BiCMOS process technology, internal synchronous rectification, variable frequency operation, and low supply current make the ML4851 ideal for 1 cell applications. The ML4851 is capable of start-up with input voltages as low as 1V and is available in 5V and 3.3V output versions with output voltage...
