微源半导体 LP54331 ESOP8 32V/3A同步BUCK开关变换器

概述

The LP54331 is a synchronous buck converter supporting up to 3A output current. The LP54331X employs an adaptive constant-on-time (COT) control scheme to achieve fast load transient response. The external components are minimized, requiring only one inductor, two resistors, and two capacitors.

The LP54331 supports both aluminum polymer capacitors and ceramic capacitors without extra compensation components.

The LP54331 integrates PFM (Pulse Frequency Modulation) operation, which helps maintain the system efficiency at light load. 

The LP54331 also integrates multiple protection functions, i.e., over-current protection (OCP), over-temperature protection (OTP), under-voltage lockout (UVLO), output over-voltage protection (OVP),and short circuit protection (SCP).
