300kHz Dual, 180° Out-of-Phase, Step-Down PWM and Single Linear Controller

The ISL6443A is a high-performance, triple-output controller

optimized for converting wall adapter, battery or network

Features

• Wide Input Supply Voltage Range

- Variable 5.6V to 24V

intermediate bus DC input supplies into the system supply

voltages required for a wide variety of applications. Each

output is adjustable down to 0.8V. The two PWMs are

synchronized at 180° out-of-phase, thus reducing the RMS

input current and ripple voltage.

- Fixed 4.5V to 5.6V

• Three Independently Programmable Output Voltages

• Switching Frequency . . . . . . . . . . . . . . . . . . . . . . .300kHz

• Out-of-Phase PWM Controller Operation

The ISL6443A incorporates several protection features. An

adjustable overcurrent protection circuit monitors the output

current by sensing the voltage drop across the lower

MOSFET. Hiccup mode overcurrent operation protects the

DC/DC components from damage during output

- Reduces Required Input Capacitance and Power

Supply Induced Loads

• No External Current Sense Resistor

overload/short circuit conditions. Each PWM has an

independent logic-level shutdown input (SD1 and SD2).

- Uses Lower MOSFET’s r

DS(ON)

• Bidirectional Frequency Synchronization for

Synchronizing Multiple ISL6443As

A single PGOOD signal is issued when soft-start is complete

on both PWM controllers and their outputs are within 10% of

the set point and the linear regulator output is greater than

75% of its setpoint. Thermal shutdown circuitry turns off the

device if the junction temperature exceeds +150°C.

• Programmable Soft-Start

• Extensive Circuit Protection Functions

- UVLO

- Near Chip Scale Package Footprint, which Improves

PCB Efficiency and has a Thinner Profile

Add “-TK” suffix for tape and reel. Please refer to TB347 for details

on reel specifications.

• Pb-Free (RoHS Compliant)

NOTE: These Intersil Pb-free plastic packaged products employ

special Pb-free material sets, molding compounds/die attach

materials, and 100% matte tin plate plus anneal (e3 termination

finish, which is RoHS compliant and compatible with both SnPb and

Pb-free soldering operations). Intersil Pb-free products are MSL

classified at Pb-free peak reflow temperatures that meet or exceed

the Pb-free requirements of IPC/JEDEC J STD-020.

Applications

• Power Supplies with Multiple Outputs

• xDSL Modems/Routers

• DSP, ASIC, and FPGA Power Supplies

• Set-Top Boxes

• Dual Output Supplies for DSP, Memory, Logic, µP Core

and I/O

• Telecom Systems
