Product Details
RS PRO DC-to-DC Switching Regulators, K78 series
Introducing the RS PRO K78 range Switching Regulators, a series of wide input voltage non-isolated and regulated singe output converters. These high-quality switching regulators are a compact surface mount device solution, with the added benefit of being able to perform load conversions for greater flexibility. These RS PRO regulated converters have a low loss and short circuit protection, making them highly efficient and economical, and additionally making them ideal for use in instrumentation, IoT and a wide variety of battery-powered applications.
Features and Benefits:
- The RS PRO regulators offer high efficiency of up to 95%
- No-load input current as low as 0.2mA
- Operating ambient temperature range -40°C to +85 °C
- Output short-circuit protection
- Compact SMD (Surface Mount Device) Package
- 3 Year Warranty
Applications:
Switching regulators are circuits that are easily able to take energy from an input voltage source and push them into the output by using an electrical switch and controller. This switch and controller have the ability to ’regulate’ the rate at which the energy is moved to the output. The main benefit of switching regulators is that they work at a greater efficiency than their linear counterparts, making them more economical and better to drive higher input voltages in a wide variety of power management applications. Switching regulators are commonly used in:
- Mobile phones
- Games consoles
- Computers and laptops
- Digital cameras
- Power supplies
Approvals and Certifications:
- EN62368 Approved
- CE Certified
