Low power point-of-load DC/DC converters

High efficiency conversion for low-current, space-constrained applications

TI's portfolio of low power point-of-load DC/DC converters features high efficiency across the load spectrum for space-constrained applications. Fueled by DCS Control™ technology, this family provides low quiescent current and low BOM count for both battery- and line-powered applications up to 17V input voltage and 6A output current.

Ultra low power

To further increase battery lifetime in wearable and IoT applications, TI's low power DC/DC converter portfolio offers devices with quiescent current (Iq) in the sub 3uA range.

High power density

While DCS Control limits the total number of external components, advanced packaging technologies, like 1.5 x 1.5 QFN and SOT563 minimize overall solution size.

Fully-featured

Precision enable, forced-PWM and output discharge are a few examples of advanced features you will find in the low power point-of-load portfolio to help you solve complex DC/DC design challenges.

What is DCS Control?

TI's DCS Control architecture (Direct Control with seamless transition into power save mode) is an advanced regulation topology that combines hysteretic, voltage and current mode control.

The topology supports pulse width modulation (PWM) for medium and heavy load conditions and has a power save mode to maintain high efficiency at light load operation. It also avoids increased voltage ripple and random jitter by seamlessly transitioning between PWM and power save modes.

Benefits and features
 
  • High output-voltage accuracy through seamless transition between PWM to power save mode
  • Excellent DC-voltage and load-transient regulation, combined with low output voltage ripple
  • Small footprint and BOM count, cost-comprehensive external components like low-ESR capacitors
  • Robust design that tolerates large output capacitance
  • Highest accuracy and lowest quiescent current
