The STR-V600 series is a power IC for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC in one package.
The SIP8L full mold package features low height and creeping distance of 4mm or longer between high and low voltage pin bases.
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.
The rich set of protection features helps to realize low component count, and high performance-to-cost power
