RD0004 (RICHTEK)

The LOAD TRANSIENT TOOL from Richtek is a handy tool for testing stability of voltage regulators. It can generate very fast load steps (approximately 500nsec rise/fall times) and can be used to quickly verify pulse load behaviour of voltage regulators. This tool can be used to check DC to DC converter stability, layout resonance and input supply ringing. 7 different pulse load resistors can be selected via jumpers and an adjustable power resistor is used for setting the static load level. Pulse load frequency and duty cycle can be adjusted via pushbuttons. The tool is battery powered which makes it easy to apply at any point in your application. The Richtek Load Transient Tool contains a microcontroller that switches a MOSFET on and off with a certain duty cycle.
