Features

• Efficiency up to 95%, no need for heatsinks
• 4.5 - 36VDC wide input voltage
- -40°C to +90°C ambient operation without derating
- Pin compatible with 78 series regulators
• Non isolated DC/DC converter
- Undervoltage and short circuit protection

Switching Regulator

Description

The R-78K-1.0 series is a switching regulator module that has been designed to offer all the advantages of a switching regulator (high efficiency, wide input range, accurate output voltage regulation) but with a low cost for production quantities. Due to the R-78K-1.0's high efficiency of up to 95% no heat-sink is required, and operation from -40 to 90°C is possible with slight derating. The compact TO-220 compatible SIP3 package measures only 11.5 x 7.55 x 10.2mm, so it saves precious board space.

Short Circuit Input Current 50mA max.

Optional Diode Protection Circuit

Add a blocking diode to Vout if current can flow backwards into the output, as this can damage the converter when it is powered down.

The diode can either be fitted across the device if the source is low impedance or fitted in series with the output (recommended).
