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 direct replacements for the LM78 series three-terminal linear regulators, with the added benefit of being able to perform load conversions for greater flexibility. These RS PRO regulated converters have a low ripple and standby power consumption, making them highly efficient to work at full load without the need for a heat sink, 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

Pin compatible with RS PRO LM78xx series as a direct replacement voltage regulator

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:

IEC60950, UL60950, EN60950 Approved

CE Certified
