RT8120DGSP

Overview

The RT8120DGSP is a single-phase synchronous buck PWM DC/DC controller manufactured by Richtek Technology Corporation. It is designed to drive two N-MOSFETs for high-efficiency power conversion. The device operates with an input voltage range of 3V to 13.2V and features a fixed switching frequency of 300kHz. It offers a maximum duty cycle of 85% and includes control characteristics such as enable and phase control. The component is housed in an 8-SOP-EP package with a bare pad, suitable for surface mount installation. It supports a wide operating temperature range from -40°C to 85°C.

Feature Summary

Single-phase synchronous buck topology designed to drive external N-MOSFETs
Internal precision reference voltage for accurate low-voltage output regulation
Integrated enable and phase control capabilities for system management

Applications

Typical application circuits for single-phase synchronous buck PWM controllers
Low voltage requirement regulation systems using internal reference
General DC/DC step-down converter designs

Procurement Notes

Verify the specific suffix DGSP against the manufacturer's official datasheet to confirm pinout and electrical specifications. Ensure compatibility with the required 8-SOP-EP package footprint. Confirm that the 300kHz switching frequency aligns with the target design constraints. Check for any recent product change notifications or end-of-life announcements from Richtek Technology Corporation before finalizing procurement plans.

Selection Notes

Select this component when a synchronous buck controller is required for input voltages between 3V and 13.2V. The 300kHz frequency is suitable for balancing efficiency and passive component size. Consider the 8-SOP-EP package for thermal performance and board space constraints. Ensure the design can accommodate the external N-MOSFETs driven by this controller. Verify that the -40°C to 85°C operating range meets the environmental requirements of the application.

Part Context

The RT8120 series consists of single-phase synchronous buck PWM controllers intended for driving external N-MOSFETs. These devices provide programmable output voltage regulation through an internal reference. The family supports various packaging options including SOP-EP formats. They are part of Richtek's portfolio of power management integrated circuits focused on efficient DC/DC conversion solutions.
