Datasheet

The K78 1A series of non-isolated switching regulators from Mornsun are now available at PowerPax. This new range complements the 500mA series and extends the range of application for this product family. This series is designed to meet the greater current requirements found in many applications and is provided in a 3-Pin SIP package that is compatible with the standard linear LM78XX (TO-220 package) regulator.

The regulators provide excellent levels of efficiency (up to 96%), are very small and do not require any form of heat sink. The no-load input current takes into account the need for the highest possible efficiency in all conditions and is typically 0.1mA.

These regulators have a wide input voltage range, 6 to 36V DC, and deliver precise positive output voltages in the range of 3.3 to 15V DC.

They can also be configured to provide negative voltage outputs. Output voltage accuracy is typically ±2% with line regulation of ±0.2% typ, load regulation of ±0.4% typ and ripple & noise of typically 20mV P-P (20Mhz bandwidth).

The output transient recovery time is typically 0.1mS and the output features continuous short circuit protection with self-recovery.

This series has an MTBF of 2000K hr’s (MIL-HDBK-217F @ 25°C) and features an operating temperature range of -40°C to +85°C (de-rating above +70°C). They meet UL60950 and EN60950 safety requirements.

These regulators are suited to many application including, but not limited to, industrial control systems, instrumentation, digital systems, electricity monitoring & control and battery powered systems.

They offer a cost effective solution with lead times of typically 4 weeks for production volumes and samples generally available from stock.
