MP2152D

2.5V to 5.5V, 2A Synchronous, Step-Down

Converter with Fast Output Discharge

DESCRIPTION

FEATURES

The MP2152D is a monolithic, step-down switch-

mode converter with integrated internal power

MOSFETs. It can achieve up to 2A of continuous

output current (I_OUT) across a wide 2.5V to 5.5V

input voltage (V_IN) range, with excellent load and

line regulation. The output voltage (V_OUT) can be

regulated to as low as 0.6V.

•

Wide 2.5V to 5.5V Operating Input Voltage

(V_IN) Range

Up to 2A Output Current (I_OUT)

Adjustable Output Voltage (V_OUT) from 0.6V

25μA Low Quiescent Current (I_Q)

1.1MHz Switching Frequency (f_SW)

Enable (EN) for Power Sequencing

1% Feedback (FB) Accuracy

75mΩ and 45mΩ Internal Power MOSFETs

100% Duty Cycle

Fast Output Discharge

Output Over-Voltage Protection (OVP)

Short-Circuit Protection (SCP) with Hiccup

Mode

Available in an SOT563 Package or

UTQFN-6 (1.2mmx1.6mm) Package

•

The device is ideal for a wide range of

applications, including solid-state drives (SSDs),

portable devices, as well as other low-power and

low-voltage systems.

Constant-on-time (COT) control provides fast

transient response and eases loop stabilization.

Full protection features include cycle-by-cycle

over-current protection (OCP), over-voltage

protection (OVP), short-circuit protection (SCP)

with hiccup mode, and thermal shutdown.

•

Optimized Performance with MPS

Inductor MPL-AL4020 Series

The MP2152D requires a minimal number of

readily available, standard external components,

and is available in ultra-small SOT563 package

and UTQFN-6 (1.2mmx1.6mm) package.
