Key Features
- 70 V maximum input voltage with 2 A continuous output current, enabling step-down conversion from high-voltage industrial rails down to regulated outputs
- Synchronous buck topology with integrated high-side and low-side MOSFETs eliminating external switching devices and reducing BOM count
- Wide input voltage range supporting 24 V and 48 V industrial bus standards with high conversion efficiency for thermal-constrained designs
Applications
MIC28512-2YFL T5 is used in industrial power supply designs that step down 24 V to 70 V input rails to regulated 3.3 V, 5 V, or 12 V outputs at up to 2 A. Its integrated synchronous MOSFETs make it suitable for DIN rail power modules, field instrumentation, and motor drive auxiliary supplies where a compact, high-efficiency regulator is required. The wide input range accommodates both 24 V and 48 V bus standards common in industrial automation and building control systems.

Frequently Asked Questions
What input voltage and output current does MIC28512-2YFL T5 support for industrial power designs?
MIC28512-2YFL T5 accepts input voltages up to 70 V and delivers up to 2 A continuous output current, making it suitable for stepping down 24 V or 48 V industrial bus rails to logic-level voltages with integrated synchronous switching.
How does the synchronous buck topology in MIC28512-2YFL T5 improve efficiency versus non-synchronous designs?
MIC28512-2YFL T5 integrates both high-side and low-side MOSFETs in a synchronous buck configuration, reducing conduction losses compared to non-synchronous designs with a diode, typically improving efficiency by 3% to 8% at 2 A output current.
Which industrial supply voltage standards can MIC28512-2YFL T5 regulate from?
MIC28512-2YFL T5 covers 24 V and 48 V bus standards common in industrial automation, as well as inputs up to 70 V seen in motor drive and solar-powered field equipment, providing a single regulator solution across multiple voltage rails.
What is the package type for MIC28512-2YFL T5 and what thermal considerations apply at 2 A?
MIC28512-2YFL T5 uses a compact surface-mount package. At 2 A output current, adequate PCB copper pour and thermal vias are recommended to maintain junction temperature below the 125°C maximum, especially when switching from inputs near 70 V.
