The MAX77887 is a high-efficiency nano power buckboost converter with an input voltage monitoring feature, ensuring that the battery voltage does not drop below the pre-set threshold levels to protect the battery.
The converter operates on an input supply between 1.8V and 5.5V. Output voltage between 1.8V and 5.2V is configured through a resistor connected to the hardware control pin, RSEL1. It can operate in CCM, Skip, and Low Power Mode to ensure maximum efficiency over a wide range of load currents.
MAX77887 offers two unique hardware control pins RSEL1 and SEL2. The resistor connected at SEL1 (RSEL1) selects the predefined output voltage from 1.8V to 5.2V as OUT. The resistor connected at SEL2 (RSEL2) allows the configuration of two different Switching Current Limit (ILIM) levels and 16 Input Voltage Monitoring Threshold levels.
The MAX77887 is available in 1.36mm x 1.36mm, 9- bump, 0.4mm pitch, wafer-level package (WLP).
