LOWPOWER(微源半导体)Китай

The LP6450X is a synchronous buck converter supporting up to 2A output current. The LP6450X 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 LP6450X supports both aluminum polymer capacitors and ceramic capacitors without extra compensation components. The LP6450X integrates PFM (Pulse Frequency Modulation) operation, which helps maintain the system efficiency at light load. The LP6450X also integrates multiple protection functions, i.e., over-current protection (OCP), over-temperature protection (OTP), undder-voltage lockout (UVLO), and short circuit protection (SCP). The LP6450X is available in a small 6-pin 1.6mmΧ2.9mm SOT23-6 package.
