Description
General part information
MAX77505 Series
The MAX77505 is a low-quiescent current (800nA typ), high-efficiency hysteretic buck converter operating from a 2.5V to 16V input voltage range. The device offers high efficiency over the entire load range. Hence, it is ideal for either a primary battery or four alkaline batterypowered applications, which require long standby/idling time with short working time, such as asset tracking and door-lock devices.A resistor (RSEL) selects one of thirty preset output voltages between 0.8V and 5.5V. The device has input undervoltage lockout, cycle-by-cycle switch current limit, and thermal shutdown to protect the system and the device itself. The device is available in a 10-lead FC2QFN package (2.0mm x 2.0mm x 0.55mm).APPLICATIONS2-3 Cell Li+ Battery Applications4-Cell Alkaline Battery ApplicationsIoT, Wearable DevicesSmart Meter, Door Locks, Asset Trackers, etc.
