DATASHEET ISL6446 Dual (180°Out-of-Phase) PWM and Linear Controller The ISL6446 is a high-performance, triple output controller that provides a single high-frequency power solution primarily for broadband, DSL and networking applications.
This device integrates complete control, monitoring and protection functions for two synchronous buck PWM controllers and one linear controller.
Input voltage ripple and total RMS input current is substantially reduced by synchronized 180° out-of-phase operation of the two PWMs.
The two PWM buck converters provide simple voltage mode control.
The output voltage of the converters can be precisely regulated to as low as 0.
6V, with a maximum tolerance of ±1.
