STR-A6059H

The STR-A6000 series are power ICs for switching power supplies, incorporating a power MOSFET and a currentmode PWM controller IC in one package.
To achieve low power consumption, the product includes a startup circuit and a standby function in the controller.
The switching modes are automatically changed according to load conditions so that the PWM mode is in normal operation and the burst mode is in light load condition.
Rich set of protection features help realize low component count, and high performance-to-cost power supply.

Features

    ・Current mode PWM control
    ・Brown-in and brown-out function
    ・Auto standby function
