Overview
The RT8525DGQW is a current mode boost controller manufactured by Richtek USA Inc. It operates within an input voltage range of 4.5V to 25V and supports a switching frequency from 50 kHz to 600 kHz. The device features a maximum duty cycle of 90% and provides an adjustable output voltage with a typical feedback voltage of 1.25V. It delivers an output current capability of 100 mA and functions at temperatures between -40°C and +85°C. Packaged in a 12-WDFN (3x3) format, it includes programmable soft-start and overvoltage protection.
Feature Summary
- Supports wide input voltage ranges up to 25V for flexible power supply integration
- Features programmable switching frequency and soft-start time for optimized transient response
- Includes comprehensive protection mechanisms such as output overvoltage and undervoltage protection
Applications
- Wide output voltage range applications requiring external N-MOSFET control
- General purpose step-up converter designs
- Battery-powered systems requiring efficient voltage boosting
Procurement Notes
Verify the specific suffix DGQW corresponds to the WDFN-12 package and green lead plating configuration. Confirm that the ordering information matches the required moisture sensitivity level and RoHS compliance status. Ensure the component is sourced from authorized distributors to guarantee authenticity and proper handling during storage.
Selection Notes
Select this controller when designing high-voltage boost converters requiring precise current mode control. Consider the external N-MOSFET selection for optimal performance given the 100mA output limit. Evaluate the thermal requirements of the 12-WDFN package against the expected operating temperature range of -40°C to +85°C.
Part Context
This component belongs to the RT8525 family of current mode boost controllers. It is designed for applications needing a wide input voltage range and adjustable output parameters. The device integrates essential protection features while maintaining a compact footprint suitable for space-constrained electronic designs.
Replacement Considerations
RT8525DN-A is listed as an alias for this part number. Verify pinout compatibility and electrical specifications before substituting with other boost controllers from different manufacturers.
