ML4851 Datasheet - Micro Linear

ML4851 Low Current / Voltage Boost Regulator

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 combination of BiCMOS process technology, internal synchronous rectification, varia.
