The RT8108 series are single-phase synchronous buck PWM DC-DC controllers designed to drive two N-MOSFETs. They provide a highly accurate, programmable output voltage precisely regulated to low voltage requirement with an internal 0.6V or 0.8V reference.
The RT8108 series use a single feedback loop voltage mode PWM control for fast transient response. The high driving capability makes it suitable for large output current applications. An oscillator with fixed frequency 200kHz / 300kHz / 500kHz reduces the component size of the external inductor and capacitor for saving PCB board area and cost.
The RT8108 series integrate complete protection functions such as OCP, OVP and OTP UVP into SOP-8 and SOP-8 (Exposed Pad) surface mount packages.
