LLC resonant controller achieves 90 percent efficiency with a 10 percent load

October 24, 2017 By Aimee Kalnoskas

resonant controller

The first in a family of new high-performance LLC controllers, TI’s new UCC256301 inductor-inductor-capacitor (LLC) resonant controller enables standby power of less than 40 mW when fully regulating the system output, while also performing better than industry efficiency requirements. By delivering the fastest transient response plus robust fault-protection features such as zero current switching avoidance, […]

Choosing a reference voltage for an ADC

August 30, 2017 By Janet Heath

Analog-to-digital converters (ADCs) need a reference voltage (VREF) input in order to operate properly. ADCs convert analog inputs that can vary from zero volts on up to a maximum voltage level that is called the reference voltage. The reference voltage determines the ceiling of what the ADC can convert, and is essentially the yardstick against […]

How to select input capacitors for a buck converter

August 28, 2016 By Aimee Kalnoskas

by Maniing Xie, System Application Engineer, Power Design Systems, Texas Instruments Electromagnetic interference (EMI) can create serious issues for manufacturers in an industrial environment. A buck converter generates a pulsating ripple current with high di/dt at the input. Without input capacitors, ripple current is supplied by the upper power source. Printed circuit board (PCB) resistance […]

Automatic decay scheme for stepper motor current regulation

July 12, 2016 By Aimee Kalnoskas

by Rakesh Raja and Sudhir Nagaraj  || Closed-loop current regulation in stepper motors plays a major role in determining the accuracy and smoothness of motor motion. The scheme of current control also determines the power efficiency of the motor drive system. A typical pulse-width modulation (PWM) control loop used today has a suite of fixed-decay […]
