Dual 3A/Single 6A Step-Down DC/DC Power Module

The ISL8203M is an integrated step-down power module rated

for dual 3A output current or 6A current sharing operation.

Optimized for generating low output voltages down to 0.8V, the

ISL8203M is ideal for any low power low voltage applications.

The supply voltage range is from 2.85V to 6V. The two

channels are 180° out-of-phase for input RMS current and EMI

reduction. Each channel is capable of 3A output current. They

can be combined to form a single 6A output in current sharing

mode. While in current sharing mode, the interleaving of the

two channels reduces input and output voltage ripple.

Features

• Dual 3A and single 6A switching power supply

• High efficiency, up to 95%

• Input voltage range: 2.85V to 6V

• Output voltage range: 0.8V to 5V

• Internal digital soft-start: 1.5ms

• External synchronization up to 4MHz

• Compact size: 9.0mmx6.5mmx1.83mm

The ISL8203M offers an independent Power-Good (PG) signal

for each channel. When shut down, the ISL8203M discharges

the output capacitor. Other features include internal digital

soft-start, enable for power sequence, overcurrent protection

and over-temperature protection.

• Peak current limiting and hiccup mode short-circuit

protection

• Overcurrent protection

Applications

The ISL8203M integrates a PWM controller, synchronous

switching MOSFETs, inductors and passive components to

maximize efficiency and minimize external component count.

The ISL8203M is available in a thermally-enhanced, compact

QFN package.

• µC/µP, FPGA and DSP power

• Plug-in DC/DC modules for routers and switchers

• Test and measurement systems

• Barcode reader
