MP2349

24V, 6.5A, Low-I_Q, Synchronous

Buck Converter with Mode Selection

DESCRIPTION

FEATURES

The MP2349 is a fully integrated, high-

frequency, synchronous, rectified, step-down

switch-mode converter. It offers a very compact

solution to achieve up to 6.5A of continuous

output current (I_OUT) and 7.5A of peak output

current (I_{OUT_MAX}) across a wide input voltage

(V_IN) range.

•

Wide 4.5V to 24V Operating Input Voltage

(V_IN) Range

105μA Low Quiescent Current (I_Q)

•

6.5A Continuous Output Current (I_OUT

7.5A Peak Output Current (I_{OUT_MAX}

)

Adaptive Constant-On-Time (COT) for Fast

Transient Response

•

DC Auto-Tune Loop

Low On Resistance (R_DS(ON)) Internal Power

MOSFETs

Proprietary Switching Loss Reduction

Technology

Selectable Forced Continuous Conduction

Mode (FCCM), Automatic Pulse-Frequency

Modulation (PFM)/Pulse-Width Modulation

(PWM) Mode, and Ultrasonic Mode (USM)

Fixed 700kHz Switching Frequency (f_SW)

Stable with POSCAP and Ceramic

Capacitors

Internal Soft Start (SS)

Output Discharge

Over-Current Protection (OCP), Over-

Voltage Protection (OVP), Under-Voltage

Protection (UVP), and Thermal Shutdown

with Automatic Retry

The MP2349 operates at high efficiency across

a wide I_OUTload range based on MPS’s

proprietary switching loss reduction technology

and internal, low on resistance (R_DS(ON)) power

MOSFETs.

•

Adaptive constant-on-time (COT) control

provides fast transient response and eases loop

stabilization. The DC auto-tune loop combined

with the remote differential sense provides good

load and line regulation.

•

Full protection features include over-current

protection (OCP), over-voltage protection

(OVP), under-voltage protection (UVP), and

thermal shutdown.

•

The MP2349 requires a minimal number of

external components, and is available in a

QFN-11 (2mmx2mm) package.
