LP6452A 微源18V2A同步降压转化器IC 科瑞芯电子供应
General Description
The LP6452AT/F is a synchronous buck converter supporting up to 2A output current. The LP6452AT/F 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 LP6452AT/F supports both aluminum polymer capacitors and ceramic capacitors without extra compensation components.
The LP6452AT/F 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).
The LP6452AT/F is available in a small 6-pin 1.6mmx1.6mm SOT563 package.
Applications
● Industrial PC
● Network/digital video recorder (NVR/DVR)
