ISL6446IAZ-T7A 产品详情

The ISL6446IAZ-T7A 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 ±1.5% over-temperature and line variations. Programmable switching frequency down to 100kHz provides optimized low cost solution for ATX power supplies. It’s also able to operate up to 2.5MHz to deliver compact solutions. The linear controller provides a low-current output.Each PWM controller has soft-start and independent enable functions combined on a single pin. A capacitor from SS/EN to ground sets the soft-start time; pulling SS/EN pin below 1V disables the controller. Both outputs can soft-start into a prebiased load.The ISL6446IAZ-T7A incorporates robust protection features. An adjustable overcurrent protection circuit monitors the output current by sensing the voltage drop across the upper MOSFET rDS(ON). Latch-off mode overcurrent operation protects the DC/DC converters from damage under overload and short-circuit conditions. A PGOOD signal is issued when soft-start is complete and PWM outputs are within 10% of their regulated values and the linear regulator output is higher than 75% of its nominal value. Thermal shutdown circuitry turns the device off if the IC temperature exceeds +150°C.
