STR-A6053M

The STR-A6000 series are power ICs for switching power supplies, incorporating a power MOSFET and a currentmode PWM controll 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.
