S-8357 Overview
S-8355/56/57/58 Series STEP-UP, SUPER-SMALL PACKAGE, 600 kHz, PWM CONTROL or .sii-ic. With an external low-ON-resistance Nch Power MOS, this product is ideal for applications requiring high efficiency and a high output current. The S-8355/57 Series realizes low ripple, high efficiency, and excellent transient characteristics due to its PWM control circuit whose duty ratio can be varied linearly from 0 to 83% (from 0...
