MP2328C

High-Efficiency, 28V, 2A, 450kHz,

Synchronous Step-Down Converter

with PG, SS, and Forced CCM

DESCRIPTION

FEATURES

The MP2328C is a fully integrated, high-

frequency, synchronous, rectified, step-down

switch-mode converter with internal power

MOSFETs. It offers a very compact solution to

•

Wide 4.5V to 28V Operating Input Voltage

(V_IN) Range

Wide 0.5V to 16V Output Voltage (V_OUT

Range

)

achieve 2A of continuous output current (I_OUT

)

±1.5% Internal Reference Accuracy Over-

Temperature (OT)

130mΩ/60mΩ Low R_DS(ON)Internal Power

MOSFETs

across a wide input voltage (V_IN) range, with

excellent load and line regulation. The

MP2328C offers synchronous mode operation

for high efficiency across the wide I_OUTload

range.

•

>92% Efficiency for 24V to 5V/2A Condition

Fast Load Transient Response

450kHz Switching Frequency (f_SW)

t_ONExtension to Improve Dropout

Configurable Soft-Start Time (t_SS)

Forced Continuous Conduction Mode

(FCCM)

Power Good (PG) Indication

Over-Current Protection (OCP) with Hiccup

Mode

Constant-on-time (COT) control provides very

fast transient response and easy loop design,

as well as tight output regulation.

Full protection features include short-circuit

protection (SCP), over-current protection (OCP),

under-voltage protection (UVP), and thermal

shutdown.
