MP4562

60V, 2A Step-Down Converter with

Configurable Frequency Up to 2.5MHz

in a TSOT23-8 Package

DESCRIPTION

FEATURES

The MP4562 is a configurable-frequency, step-

down converter with an integrated, high-voltage

high-side MOSFET (HS-FET). It provides up to

2A of output current (I_OUT) across a 4.5V to 60V

input voltage (V_IN) range.

•

4.5V to 60V Input Voltage (V_IN) Range

0.8V to 30V Output Voltage (V_OUT) Range

30μA Low Quiescent Current (I_Q)

99% Duty Low-Dropout Regulation

120mΩ Integrated, Internal High-Side

MOSFET (HS-FET)

100kHz to 2.5MHz Switching Frequency

(f_SW)

Internal Loop Compensation

Peak current mode control with internal

compensation provides fast transient response

and easy loop design. It supports a wide 100kHz

to 2.5MHz switching frequency (f_SW) range. The

device provides a small-sized, high-efficiency

solution for a wide variety of step-down

applications.

•

Configurable External Soft Start (SS)

Configurable Accurate Under-Voltage

Lockout (UVLO) Hysteresis

•

Short-Circuit Protection (SCP) with

Frequency Foldback and Current Limit

(I_LIMIT) Foldback

Feedback (FB) Over-Voltage Protection

(OVP) (FB OVP Threshold = 110% of V_REF

Over-Temperature Protection (OTP) (OTP

Rising Threshold = 150°C)

The MP4562 features cycle-by-cycle current limit

(I_LIMIT) foldback and frequency foldback, which

protects against overload and short circuit

conditions, regardless of whether V_INis high. The

frequency stretch-down function improves
