深圳市科瑞芯电子供应 LP6451F 微源18V3A同步降压转换器
General description
The LP6451F is a synchronous buck converter supporting up to 3A output current. The LP6451F 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 LP6451F supports both aluminum polymer capacitors and ceramic capacitors without extra compensation components.
The LP6451F integrates PFM (Pulse Frequency Modulation) operation, which helps maintain the system efficiency at light load. The LP6451F also integrates multiple protection functions, i.e., over-current protection (OCP), overtemperature protection (OTP), under-voltage lockout (UVLO), and short circuit protection (SCP).
Applications
● Industrial PC
● Network/digital video recorder (NVR/DVR)
● TV and TV box
● 12V Industrial bus applications
