A power boost scheme for portable lithium-ion devices such as Bluetooth audio
Publisher: Administrator Date：2020-12-03
This is a highly integrated Boost converter that can be widely used in portable applications. The product uses a synchronous high-efficiency step-up boost converter with 10A switching current capability, which can provide an output voltage of up to 20V. The integrated low Rds (on) MOSFET can minimize the physical footprint, maximize efficiency, and reduce power consumption. Constant current control is used to protect equipment from overshoot under unnecessary conditions. Built-in loop compensation simplifies the circuit and design. PFM is dedicated to maintaining high efficiency at light loads. In addition, robustness is ensured by thermal protection and undervoltage lockout.
