ISL8203MEVAL2Z
Dual 3A/Single 6A Step-Down DC/DC Power Module

The ISL8203M is a complete, dual step-down power module with integrated PWM controller, synchronous switching MOSFETs, inductors, and passives.

 The ISL8203M is rated for dual 3A output current or 6A current sharing operation with an input range of 2.85V to 6V. The two channels are 180° out-of-phase for input RMS current and EMI reduction.

The simplicity of the ISL8203M is its off the shelf, unassisted implementation. It is easy to apply this complete step-down power module to any low voltage low power application.

The ISL8203MEVAL2Z evaluation board is designed to demonstrate the performance of the ISL8203M. The board is by default set up to demonstrate two 3A outputs independently, and can also be easily set up for current sharing 6A by changing placeholder resistors.
