LP6462X

30V/2A Synchronous BUCK Switching Converter

Features

General Description

⚫Wide input voltage range: 4.5V – 30V

The LP6462 is a synchronous buck converter supporting

up to 2A output current. The LP6462 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.

⚫High efficiency operation

-Integrated an 75-mΩ LS-MOSFET and an 110-mΩ

HS-MOSFET

-91% efficiency at 2A load from 12V to 5V conversion

⚫Automatic PFM mode at light load (LP6462, LP6462H)

and FPWM mode over all load range (LP6462F,

LP6462HF)

The LP6462 supports both aluminum polymer capacitors

and ceramic capacitors without extra compensation

components.

⚫±1% Vref accuracy

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), over-

temperature protection (OTP), under-voltage lockout

(UVLO), and short circuit protection (SCP).

⚫Typical 1.0-MHz switching frequency (LP6462H),

500kHz switching frequency (LP6462)

⚫COT control scheme with fast load transient response

⚫Hiccup protection

⚫Integrated UVLO, OVP, OCP, SCP, and OTP

protections

The LP6462 is available in a small 6-pin 1.6mmΧ2.9mm

SOT23-6 package.

⚫600us typical soft-start time

⚫1.6mm Χ 2.9mm SOT23-6 package

⚫RoHS Compliant and 100% Lead (Pb) Free
