S-8365AABBA-I6T1U2

Product Summary

The S-8365AABBA-I6T1U2 is a CMOS step-up switching regulator controller which mainly consists of a reference voltage source, an oscillation circuit, an error amplifier, a phase compensation circuit, a timer latch short-circuit protectioncircuit, a PWM control circuit. 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-8365AABBA-I6T1U2 efficiently works on voltage’s condition of large I/O difference due to the PWM control circuit linearly varies the duty ratio to 90%. The applications of the S-8365AABBA-I6T1U2 include MP3 players, digital audio players, Digital cameras, GPS, wireless transceiver, Portable devices.
