The LM336 is a precision 2.5V shunt regulator diode that is commonly used in Voltage reference designs. It has a dynamic Impedance of 0.2Ω with a wide operating current form 400uA to 10mA. It can also operate on high frequency upto 100Hz.
The VIPER12A is a SMPS controller IC that consists of a PWM controller with a power MOSFET. It can take in AC voltage from 85V to 265V and convert to low level voltage like 5V with output current from 10mA to 200mA.
Vicor released BCM4414 which is a new 800V, 1.5kW, isolated, 1/16 fixed-ratio Bus Converter Module able to operate from a 500V to 800V input voltage to deliver SELV output voltages with 97.7% peak efficiency.
The IRF830 is a fast switching high voltage N-Channel MOSFET with a low on-state resistance. The Mosfet has a maximum drain to source voltage of 500V. The mosfet will have a drain to source internal resistance of 1.5Ω when triggered with 10V gate voltage.
