ANALOG DEVICES MAX8569BETT+T DC-DC Switching Synchronous Boost Regulator, Fixed, 1.5 V to 5.5 V in, 3.3 V/0.2 A out, TDFN-EP-6

MAX8569B boost regulator provides up to 200mA at output voltages up to 5.5V from a 1.5V to 5.5V input source. The built-in synchronous rectifier allows for over 90% efficiency while achieving small size and low cost by eliminating the need for an external Schottky diode. The MAX8569B features a power-on reset output (active-low RST) to signal that the output has reached regulation. All devices connect the battery input to the output during shutdown, allowing the input battery to be used as a backup or real-time clock supply when the converter is off. Applications include medical diagnostic equipment, digital cameras, PDAs and smartphones, cordless phones, battery backup, PC cards, local 3.3V or 5V supply.
