The LP6454 series is a high efficiency synchronous buck converter supporting up to 4A output current and low heat. The LP6454 series 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 LP6454 series supports both aluminum polymer capacitors and ceramic capacitors without extra compensation components.
The LP6454 series integrates PFM (Pulse Frequency Modulation) operation, which helps maintain the system efficiency at light load. The LP6454 series 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 LP6454 series is available in a small 6-pin 1.6mmΧ2.9mm SOT23-6 package.
