Microchip | MIC28510YJL-TR

The MIC28510YJL TR is a part of MIC28510 Series 75 V 500 KHz Hyper Speed Control Synchronous DC/DC  adjustable-frequency, synchronous buck regulator featuring unique adaptive on-time control architecture.

The MIC28510 offers a full suite of protection features to ensure protection of the IC during fault conditions. These include undervoltage lockout to ensure proper operation under power-sag conditions, internal soft-start to reduce inrush current, foldback current limit, “hiccup” mode short-circuit protection and thermal shutdown.

Features:

• High Delta V operation (VIN = 75 V and VOUT = 0.8 V)
• Small output capacitance
• 4.5 V to 75 V voltage input
• 4 A output current capability, up to 95% efficiency
• Adjustable output down to 0.8 V
• ±1% FB accuracy
• Any Capacitor™ Stable
• Zero-ESR to high-ESR output capacitors
• 100 kHz to 500 kHz switching frequency
• Supports safe startup into a pre-biased load
• –40°C to +125°C junction temperature range
• 28-pin 5mm x 6mm MLF® package

Applications:

• Distributed power supply
• Communications/networking infrastructure
• Industrial power
• Solar energy
