Tunable Loop TM Technology
Improved footprints, transient response, and costs
The power of Tunable Loop TM is a simple implementation of a resistor and capacitor in series across the Point of Load (POL) Trim and Output pins to
optimize POL modules for multiple applications of varying demands. These very small passive devices never exceed a few kΩ resistance or a few hundred nF capacitance.
The figure below illustrates the transient response of a 12A PicoTLynx? module to a 50% load step with varying external capacitance. The maximum voltage deviation
improves from 415mV (0μF) to 235mV (3x47μF) but the control loop bandwidth drops from 78 to 21kHz, increasing the duration of the voltage excursion. This is consistent
with the reduction in control bandwidth and poorer phase margin caused by increased capacitance.
Without Tunable Loop: High deviation and reduced control bandwidth with increased output capacitance.
The goal of Tunable Loop TM is to regain the bandwidth lost with increased capacitance. If we fix the value of R Tune to 150Ω and vary C Tune from 0pF to 7500pF, we
regain control bandwidth back to 82KHz and achieve a 4 .8x reduction in voltage deviation .
With Tunable Loop?: Substantially reduced deviation through improved control bandwidth and reduced output capacitance.
Tunable Loop? achieves lower voltage deviation with significantly reduced capacitance. As an example, the 6A PicoTLynx TM module (5Vin / 1.2Vout @ 4A), with a step
load of 3A and deviation <4% (48mV) would require 3 electrolytic caps versus 3 ceramic caps with Tunable Loop TM . This results in a $0.60 reduction in external capacitor
cost and a footprint reduction of 111mm 2 achieving >3X the effective current density .
