The LP6451 is a synchronous buck converter supporting up to 3A output current. The LP6451 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 LP6451 supports both aluminum polymer capacitors and ceramic capacitors without extra compensation components. The LP6451 integrates PFM (Pulse Frequency Modulation) operation, which helps maintain the system efficiency at light load. The LP6451 also integrates multiple protection functions, i.e., over-current protection (OCP), overtemperature protection (OTP), under-voltage lockout (UVLO), and short circuit protection (SCP). The LP6451 is available in a small 6-pin 1.6×2.9mm SOT23-6 package.
