Latest switching regulators expand application potential

Complementing the proven 500mA series and extending application potential, Mornsun's latest non-isolated switching regulators are now available from PowerPax, The new K78 1A 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 range provides high levels of efficiency (up to 96%), is particularly compact and does 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. The regulators have a wide input voltage range, 6VDC to 36VDC, and deliver precise positive output voltages in the range of 3.3VDC to 15VDC. 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. The series has an MTBF of 2000K hr’s (MIL-HDBK-217F at 25C) and features an operating temperature range of -40C to +85C (de-rating above +70C). They meet UL60950 and EN60950 safety requirements. The regulators are suited to many application including, but not limited to, industrial control systems, instrumentation, digital systems, electricity monitoring & control and battery powered systems, says the company.
