Overview
The RT7753GCSGE is a PWM controller for programmable power converters, specifically designed for USB Power Delivery applications. It utilizes a Flyback topology and operates within an input voltage range of 9 V to 42 V. The device provides a single output at 12 V with a fixed switching frequency of 84 kHz. It is housed in a SOT-23-6 package and supports surface mount installation. The component functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Integrated PWM control architecture optimized for USB Power Delivery programmable power converter designs
- Supports Flyback topology for efficient isolated power conversion
- Capable of handling wide input voltage ranges suitable for various power delivery standards
Applications
- USB Power Delivery (USBPD) power supplies
- Programmable AC/DC adapters
- Flyback-based wall chargers
Procurement Notes
Verify the specific suffix 'GE' against the manufacturer's official datasheet to confirm tape and reel packaging specifications and moisture sensitivity level details. Ensure the ordering part number matches the exact RoHS compliance status and lead time requirements provided by authorized distributors. Cross-reference the Mouser number 835-RT7753GCSGE for accurate sourcing channels.
Selection Notes
Select this component when designing flyback converters requiring USB PD compatibility. The fixed 84 kHz frequency aids in EMI management. Verify that the external transformer design aligns with the 9 V to 42 V input window. Confirm that the SOT-23-6 package thermal performance meets the system's heat dissipation needs within the specified operating temperature range.
Part Context
This part belongs to Richtek's PMIC portfolio, categorized under Switching Voltage Regulators. It serves as a specialized controller for modern power delivery systems rather than a general-purpose regulator. The product line focuses on cost-effective solutions for consumer electronics and communication equipment power stages.
Replacement Considerations
The RT7753GCSD-A is listed as an alias for this part number. Verify if this variant differs only in packaging or if functional parameters remain identical before substitution.
