The LP54334 is a synchronous buck converter supporting up to 3A output current. The LP54334 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 LP54334 supports both aluminum polymer capacitors and ceramic capacitors without extra compensation components.The LP54334 integrates PFM (Pulse Frequency Modulation) operation, which helps maintain the system efficiency at light load. The LP54334 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 LP54334 is available in a ESOP-8 package.
