The high input voltage non-isolated DC-DC converters offer unique solutions for converting high-powered, variable voltages to a wide range of output voltages. The converter is a non-isolated buck-boost regulator, which employs synchronous rectification to achieve extremely high conversion efficiency. These products are suitable for use in IBA, or to provide a regulated output voltage from a variable voltage source such as a battery. They can be configured to ‘buck’ the input voltage down or ‘boost’ the input voltage up using a single external resistor.
Product Features:
• Ultra-high efficiency up to 97%
• Wide input voltage ranges: 9-60V (28V); 9-90V (28VE)
• Buck/Boost Mode available
• Maximum input/output currents up to 40A
• Suitable for use in Intermediate Bus Architectures
• On-board input and output filtering
• No minimum load requirement
• -55°C to +100°C Operating Temperature
• Remote sense and wide output voltage trim (Half‑brick only)
Battery Charging:
Key feature of Trimmable Current Limit
• Provides the power conversion platform for battery charging
• Output current limit is externally controlled for constantcurrent charging
• Current can be set with an external resistor or an active circuit
• Current analog signal provided for instrumentation and control functions
• Ideal diode output stage with zero back-drive currents prevents discharge of battery when not charging
• Output voltage set-point is independently controlled through trim pin
• Unit will smoothly transition between current and voltage modes as charging cycle needs change
