RT8110
Compact Synchronous Buck DC/DC PWM Controller
General Description
The RT8110 is a compact fixed-frequency PWM controller with integrated MOSFET drivers for single-phase synchronous buck converter.
This part features wide input voltage range operation and tiny package.
An internal pre
regulator drives an external BJT to provide regulated output voltage from the input voltage to support VCC.
Therefore, the controller can operate with wide input voltage range.
The RT8110 utilizes voltage-mode control with internal compensation to simplify the converter design.
An internal 0.
8V reference voltage allows low output voltage application.
The switching frequency is fixed at 400kHz to reduce the...
