微源半导体 LP6452ATF SOT563中的18V/2A同步BUCK开关变换器
General Description
The LP6452ATF is a synchronous buck converter supporting up to 2A output current. The LP6452ATF 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 LP6452ATF supports both aluminum polymer capacitors and ceramic capacitors without extra compensation components.
The LP6452ATF integrates PFM (Pulse Frequency Modulation) operation, which helps maintain the system efficiency at light load. The LP6452AT/F also integrates multiple protection functions, i.e., over-current protection (OCP), over-temperature protection (OTP), under-voltage lockout (UVLO), and short circuit protection (SCP).
