16V Input, 4.6A Switching Current Low IQ

Buck Converter

MAX77505

Benefits and Features

General Description

•

Input Voltage: 2.5V to 16V

Output Voltage: 0.8V to 5.5V

Long Battery Life

• 70nA Shutdown Current

• 800nA Ultra-Low Quiescent Current (I )

• 86% Efficiency at 100µA Load at 7.6V , 3.3V

• 95% Peak Efficiency at 7.6V , 3.3V

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 battery-

powered applications, which require long standby/idling

time with short working time, such as asset tracking and

door-lock devices.

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).
