ZHCSIH0B December 2017 – July 2019 LP87702-Q1
The LP87702-Q1 device integrates a boost converter with programmable output voltage from 4.9V to 5.2V in 0.1V steps, and input voltage range from 2.8V to 4V. The boost converter has flexibility to support wide range of application conditions:
Following parameters can be programmed via registers, with default values set by OTP bits unless otherwise noted:
The boost converter operates in forced PWM mode with fixed switching frequency across all load currents. When boost is disabled, boost output is isolated from the input voltage rail.
Boost converter supports an alternative operating mode as a bypass/load switch, with input voltage range from 4.5V to 5.5V. Operating mode is selected in OTP and is fixed, changing the mode on-the-fly is not supported.
