Voltage Regulators - DC DC Switching Regulators datasheet and documents for RT9277CGF

RT9277CGF

Voltage Regulators - DC DC Switching Regulators Overview

The RT9277CGF is a high-performance, low-noise step-up DC-DC converter manufactured by Richtek USA Inc. It operates with an input voltage range of 2.5V to 5.5V and provides an adjustable output voltage up to 16V. The device delivers a maximum switch current of 1.2A and supports switching frequencies of 640kHz or 1.2MHz. It features a single positive output configuration without synchronous rectification. The component is housed in an 8-MSOP package and is rated for operation between -40°C and 85°C ambient temperature.

Voltage Regulators - DC DC Switching Regulators Feature Summary

High-performance step-up DC-DC conversion with low noise characteristics
Adjustable output voltage capability within specified limits
Integrated fixed-frequency switching operation

Voltage Regulators - DC DC Switching Regulators Applications

Battery-powered portable electronic devices requiring voltage boosting
Systems needing efficient step-up regulation from single-cell lithium sources
Low-noise power supply applications for sensitive analog circuits

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'CGF' against the manufacturer's official datasheet to confirm pinout and electrical specifications match your design requirements. Note that this part number may be subject to End-of-Life (EOL) status; check the latest Product Change Notification (PCN) for availability timelines and final order dates before committing to production volumes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a non-synchronous boost topology is acceptable for the target efficiency profile. Ensure the required output voltage falls within the adjustable range supported by the external feedback network. Confirm that the 1.2A switch current limit meets the peak load demands of the application without triggering protection mechanisms.

Voltage Regulators - DC DC Switching Regulators Part Context

The RT9277CGF belongs to the RT9277 family of step-up converters. This series includes variants such as the RT9277A and RT9277B, which share similar core functionalities but may differ in fixed output voltages or specific switching frequency options. The CGF suffix typically denotes the specific package type and temperature grade defined by Richtek.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Consult the manufacturer's PCN documents for officially confirmed substitute part numbers due to the EOL status. Direct replacements must maintain compatible input/output voltage ranges and package dimensions to ensure board-level compatibility.
