- Power supplies compliant with Blue Angel standby efficiency standards
Procurement Notes
Verify the exact suffix 'SP13TR' against official STMicroelectronics documentation to confirm the specific tape-and-reel packaging and pin configuration. Ensure compatibility with the PowerSO-10 surface mount package requirements. Cross-reference the part number with the latest datasheet revision to confirm active status and any potential obsolescence notices before finalizing procurement plans.
Selection Notes
Select this component for designs requiring integrated high-voltage switching and control in a compact surface-mount package. Consider the 300 kHz maximum switching frequency for transformer size optimization. Evaluate the thermal performance within the PowerSO-10 package for the intended power level. Verify input voltage ranges and output power capabilities against the specific application requirements defined in the datasheet.
Part Context
The VIPER53 series belongs to STMicroelectronics' VIPer family of monolithic switching regulators. These devices combine power MOSFETs with intelligent control circuitry to simplify offline power supply design. The VIPER53 specifically targets applications needing high efficiency and robust protection features in a small footprint, suitable for consumer electronics and industrial equipment.
Replacement Considerations
Consult official STMicroelectronics substitution guides for verified alternatives. Check for equivalent packages such as DIP-8 if leaded options are required. Ensure electrical parameters like breakdown voltage and switching frequency match the original design specifications.
