Monolithic Power Systems Inc. HF01B02DP-LF

HF01B02DP-LF - High-Voltage Isolated Flyback Switching Controller IC

The HF01B02DP-LF from Monolithic Power Systems (MPS) is a high-performance offline AC-DC flyback switching controller IC engineered for reliable, isolated power conversion in industrial, telecom, and power supply applications up to 33W. Featuring integrated switching with 700V breakdown voltage capability and comprehensive fault protection, this controller delivers robust performance for safety-critical designs requiring galvanic isolation.

Key Features & Technical Advantages

• Isolated Flyback Topology: Provides galvanic isolation between primary and secondary for safety-critical applications including medical, industrial controls, and telecom equipment
• 700V High-Voltage Breakdown: Enables universal AC input designs (85-265VAC) with margin for transient protection
• 33W Maximum Power Output: Optimized for low-to-medium power offline converters, auxiliary supplies, and bias rails
• Integrated Multi-Layer Protection: Built-in over-load (OLP), over-temperature (OTP), and over-voltage (OVP) fault protection ensures long-term reliability
• Wide Operating Voltage Range: 8V to 20V supply voltage (Vcc/Vdd) with 11.8V start-up threshold for flexible design implementation
• Up to 150kHz Switching Frequency: High-frequency operation enables compact transformer design, reduced magnetics size, and smaller output filter components
• Through-Hole 8-DIP Package: Industry-standard 7.62mm (0.300") pitch DIP format for easy prototyping, hand assembly, and reliable wave-soldering in production
• Extended Temperature Range: -40°C to +85°C ambient operating range for industrial and automotive-adjacent applications
• RoHS & REACH Compliant: Lead-free, halogen-free construction meets global environmental and regulatory standards

Target Applications

This offline switching controller IC is ideal for AC-DC power supplies in smart meters, industrial automation controllers, home appliances, LED lighting drivers, auxiliary power modules, telecom infrastructure, battery chargers, and IoT gateway devices where isolation, efficiency, compact size, and long-term reliability are mission-critical.
