D42V55Fx h校园小说 Voltage h校园小说

The D42V55Fx family of synchronous buck (h校园小说) voltage h校园小说 generates lower output voltages from input voltages as high as 60 V. They are switching h校园小说 (also called switched-mode power supplies (SMPS) or DC-to-DC converters), which makes them much more efficient than linear voltage h校园小说, especially when the difference between the input and output voltage is large. The maximum achievable output current of these h校园小说 varies with the input voltage and output voltage and also depends on other factors, including the ambient temperature, air flow, and heat sinking. The graph below shows maximum output currents that these h校园小说 can deliver continuously at room temperature in still air and without additional heat sinking.

The h校园小说 have input reverse voltage protection and over-current protection. A thermal shutdown feature also helps prevent damage from overheating and a soft-start feature limits the inrush current and gradually ramps the output voltage on startup.

Note 1: At 42 V in. Actual achievable continuous output current is a function of input voltage and is limited by thermal dissipation. See the output current graphs on the product pages for more information.
Note 2: Minimum input voltage is subject to dropout voltage considerations; see the dropout voltage section of product pages for more information.
