科瑞芯电子供应 LP6453M 微源同步降压转化器芯片
General Description
The LP6453M is a high efficiency synchronous buck converter supporting up to 3A output current and low heat.
The LP6453M employs an adaptive constant-on-time (COT) control scheme to achieve fast load transient response and without external compensation. The external components are minimized, requiring only one inductor, two resistors, and two capacitors.
The LP6453M supports both aluminum polymer capacitors and ceramic capacitors without extra compensation components.
The LP6453M integrates PFM (Pulse Frequency Modulation) operation, which helps maintain the system efficiency at light load. LP6453M also integrates multiple protection functions, i.e., over-current protection (OCP), over-temperature 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
