General Description
The RT8120 is a single-phase synchronous buck PWM
DC-DC controller designed to drive two N-MOSFET. It
provides a highly accurate, programmable output voltage
precisely regulated to low voltage requirements with an
internal 0.8V ±1% ( option for 0.6V ±1.5%) reference. The
RT8120 uses a single feedback loop voltage mode PWM
control for fast transient response. An oscillator with fixed
frequency 300kHz reduces the external inductor and
capacitor component size for saving PCB board area. The
RT8120 provides fast transient response to satisfy high
current output applications while minimizing external
components. It is suitable for high performance graphic
processors, DDR and VTT power. The RT8120 incorporates
an externally compensated error amplifier and an internal
soft-start and output enable. The RT8120 comes in
SOP-8 and SOP-8 (Exposed Pad) packages.
