供应LP6462HF 微源高效同步降压转换器

微源半导体 LP6462HF SOT23-6 30V/2A同步降压转换器

General Description

The LP6462HF is a synchronous buck converter supporting up to 2A output current. The LP6462HF 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 LP6462HF supports both aluminum polymer capacitors and ceramic capacitors without extra compensation components.

The LP6462 integrates PFM (Pulse Frequency Modulation) operation, which helps maintain the system efficiency at light load. The LP6462 also integrates multiple protection functions, i.e., over-current protection (OCP), overtemperature protection (OTP), under-voltage lockout (UVLO), and short circuit protection (SCP).

The LP6462 is available in a small 6-pin 1.6mmx2.9mm SOT23-6 package.
