Part details & applications

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, R_SEL1. 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 R_SEL1 and _SEL2. The resistor connected at SEL1 (R_SEL1) selects the predefined output voltage from 1.8V to 5.2V as OUT. The resistor connected at SEL2 (R_SEL2) allows the configuration of two different Switching Current Limit (I_LIM) 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).
