The MAX77371 is an ultrasonic, high-performance boost converter with an input voltage range from 2.5V to 5.5V and a configurable switching current limit of up to 5.0A. The IC operates in Ultrasonic mode (fSW > 25kHz) at low loads and transitions into Skip and CCM modes of operation at higher load currents. When selected, the device can operate in forced PWM mode.
The output voltage can be widely varied between 4.5V and 10.0V.
The MAX77371 features a true shutdown mode that disconnects VIN and VOUT when the EN pin is pulled low. It also implements short circuit, overcurrent, voltage, and temperature protection features. The MAX77371 is available in a 20-bump, 0.35mm pitch wafer-level package (WLP).
APPLICATIONS
