The LP6433X is a synchronous buck converter supporting up to 3A output current. The LP6433X 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 LP6433X supports both aluminum polymer capacitors and ceramic capacitors without extra compensation components.
The LP6433X integrates PFM (Pulse Frequency Modulation) operation, which helps maintain the system efficiency at light load. The LP6433X also integrates multiple protection functions, i.e., over-current protection (OCP), over-temperature protection (OTP), under-voltage lockout (UVLO), output over-voltage protection (OVP), and short circuit protection (SCP).
The LP6433X is available in a small 6-pin 1.6mm x 2.9mm SOT23-6 package.
