RD0004

The LOAD TRANSIENT TOOL from Richtek is a handy tool for testing stability of voltage regulators. It can generate very fast load steps (~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 application. The Richtek Load Transient Tool contains a microcontroller that switches a MOSFET on and off with a certain duty cycle.

• 7 selectable 1W pulse load resistors from 0.5ohm to 22ohm
• Adjustable 10 ohm/10W resistor for static load
• Adjustable duty cycle from 0.1% to 50%
• Adjustable frequency from 15Hz to 976Hz in 4 steps
• 500nsec pulse load rise/fall times
• Highly suitable for testing DC to DC buck converters with 1V to 5V output and 1A to 5A load
• Can also be used for testing LDO, boost, buck-boost converters
• Power LED, power on/off jumper
