The LP6434SPF is a high efficiency synchronous buck converter supporting up to 4A output current and low heat.
The LP6434SPF 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, several resistors and capacitors.
The LP6434SPF supports both aluminum polymer capacitors and ceramic capacitors without extra compensation components.
The LP6434SPF integrates PFM (Pulse Frequency Modulation) operation, which helps maintain the system efficiency at light load. The LP6434SPF also integrates multiple protection functions, i.e., over-voltage protection (OVP), over-current protection (OCP), over-temperature protection (OTP), under-voltage lockout (UVLO), and short circuit protection (SCP).
The LP6434SPF is available in an 8-pin ESOP-8 package.
