Overview
The AP3790MTR-G1 is a PumpE AC/DC PSR Switcher manufactured by Diodes Incorporated, designed for flyback topology applications. It features a single output with a switching frequency of 20 kHz and an output voltage of 970 mV. The device supports an output current of 32 mA and operates within a supply voltage range of 5.2 V to 6.4 V, drawing a working supply current of 565 uA. It is housed in an SOIC-8 package and functions reliably between -40 C and +150 C.
Feature Summary
- Implements primary side regulation (PSR) for cost-effective AC/DC power conversion without secondary feedback components.
- Utilizes Flyback topology to manage power transfer efficiently in isolated converter designs.
- Integrates high-temperature operation capabilities suitable for demanding industrial environments.
Applications
- AC/DC power supplies requiring primary side regulation
- Flyback converter circuits
- Power management ICs for isolated DC-DC conversion
Procurement Notes
Verify the End-of-Life status before procurement, as the manufacturer indicates this component is obsolete and will be discontinued. Confirm regional availability restrictions, as distribution channels may not stock this item in all locations. Ensure compliance with RoHS requirements and moisture sensitivity handling protocols during storage and assembly processes.
Selection Notes
Select this component for flyback topologies requiring primary side regulation. Consider the 20 kHz switching frequency and 32 mA output capability against load requirements. Verify that the operating temperature range of -40 C to +150 C meets environmental specifications. Note the SOIC-8 package constraints for PCB layout design.
Part Context
This part belongs to the AP3790 series of AC/DC PSR Switchers from Diodes Incorporated. It falls under the PMIC category, specifically within Power Management ICs. The Pump Express branding denotes its specific regulatory architecture optimized for simplified bill-of-materials in offline power applications.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Due to the End-of-Life status, alternative sourcing requires direct consultation with the manufacturer or authorized distributors for potential obsolescence management programs.
