微源半导体 LP6453TF SOT23-6(FC) 18V/3A同步BUCK开关变换器
General Description
The LP6453TF is a high efficiency synchronous buck converter supporting up to 3A output current and low heat.
The LP6453TF 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 LP6453TF supports both aluminum polymer capacitors and ceramic capacitors without extra compensation components.
The LP6453TF integrates PFM (Pulse Frequency Modulation) operation, which helps maintain the system efficiency at light load. The LP6453TF also integrates multiple protection functions, i.e., over-current protection (OCP), over-temperature protection (OTP), under-voltage lockout (UVLO), and short circuit protection (SCP).
Features
● Wide input voltage range: 4.2V – 18V
