ZHCSIH0C December 2017 – June 2021 LP87702-Q1
The LP87702-Q1 device integrates a boost converter with programmable output voltage from 4.9 V to 5.2 V in 0.1 V steps, and input voltage range from 2.8 V to 4 V (3 V to 4 V in P87702D). The boost converter has flexibility to support wide range of application conditions:
The following parameters can be programmed through the registers, with default values set by the 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 or load switch, with input voltage range from 4.5 V to 5.5 V. Operating mode is selected in OTP and is fixed; changing the mode on-the-fly is not supported. Bypass mode is not supported in P87702D.
