With the PMIC’s wide (CDN) from Teseq has been specifically designed testing supply range of 2.7 to 5.5V, the reference board is able to use electrical fast transients (EFT) and high power bursts in large a single cell lithium battery as well as 5V power supply. in large machines, appliances and Dialog Semiconductor smart grid applications. The CDN www. novtech.com 3083-B200 easily handles high inrush currents and pulse-shaped peak currents, it can also inject DC link film capacitors rated from 550 to 1200V fast burst pulses, up to 8 kV (5/50 for power supply and inverter applications ns – 50 Ohm), into the supply lines of the equipment under test (EUT).
