Choosing a reference voltage for an ADC
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 […]

Super-compact sync buck converter on PMBus boasts gives 35-A output
Texas Instruments today introduced the industry’s highest-density, 18-V input, 35-A synchronous DC/DC buck converter, which offers full differential remote-voltage sensing and PMBus to support telemetry. TI’s TPS546C23 power converter integrates high- and low-side MOSFETs into a small-footprint package that is significantly denser than competitive devices. Designers can stack two converters in parallel to drive loads up to […]
How to select input capacitors for a buck converter
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 […]
Battery-charging considerations for low-power applications
By Tahar Allag The wearable and personal-electronics industries are booming. Devices in this market vary wildly by application and use. These multifunction devices are designed to help people in their daily activities and make their lives comfortable. They can be found in different shapes, colors, sizes, and safety measures. They may differ significantly from each […]
Fast isolated gate driver for high-voltage applications handles 5.7 kVrms
Texas Instruments introduced the industry’s fastest 5.7-kVRMS isolated dual-channel gate driver, the first of a new gate driver family in TI’s isolation portfolio. The UCC21520’s flexible, universal compatibility enables its use as an isolated driver in low-side, high-side, high-side/low-side or half-bridge power management designs. With its integrated components, advanced protection features and optimized switching performance, […]
Automatic decay scheme for stepper motor current regulation
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 […]
