MP9928

4V-60V Input, Current Mode,

Synchronous Step-Down Controller

DESCRIPTION

FEATURES

The MP9928 is a high-voltage, synchronous

step-down switching regulator controller that

can directly step down voltages from up to 60V.

The MP9928 uses PWM current control

architecture with accurate cycle-by-cycle

current limiting. It is capable of driving dual N-

channel MOSFET switches.

•

Wide 4V to 60V Operating Input Range

Dual N-Channel MOSFET Driver

Low Dropout Operation: Maximum Duty

Cycle at 99.5%

Programmable Frequency Range: 100kHz -

1000kHz

•

180º Out-of-Phase SYNCO

External Soft-Start and PG Pin

Selectable Cycle-by-Cycle Current Limit

Output Over Voltage Protection

Internal LDO with Externally Power Supply

Option

Programmable CCM and AAM Pulse-

Skipping Mode

Accuracy Over Temperature Protection

TSSOP20-EP package and QFN-20

(3mmx4mm) Package

AAM Mode (Advanced asynchronous mode)

enables non-synchronous operation and PFM

mode to optimize light load efficiency.

The operating frequency of MP9928 can be

programmed by an external resistor or

synchronized to an external clock for noise-

sensitive applications. Fault protections are

available including a precision output over

voltage protection (OVP), output over current

protection (OCP), and thermal shutdown.

•

The MP9928 is available in TSSOP20-EP

package and QFN-20 (3mmx4mm) package.

APPLICATIONS

PD Power Supply in PoE System

USB Dedicated Charging Port (DCP)

Industrial Control Systems

•

Power Supply for Linear Chargers
