ML4851 Datasheet, Micro Linear

n Guaranteed full load start-up and operation at 1V input n Maximum switching frequency > 100kHz n Pulse Frequency Modulation (PFM) and internal synchronous rectification.

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.

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 tec.
