Frequently Asked Questions

What output current can the LT3572EUF#TRPBF deliver to piezo actuators and its boost converter simultaneously?

The LT3572EUF#TRPBF provides dual piezo driver outputs each capable of 500mA peak current, and a separate 900mA boost converter output, all operable concurrently from a 2.5V to 10V input. This combination allows designers to drive high-capacitance piezoelectric transducers at full current while simultaneously powering auxiliary circuits from the boosted output, simplifying power architecture in portable haptic feedback systems.

For a wearable device running on a 3.7V Li-ion cell, how does the LT3572EUF#TRPBF supply piezo drive voltage?

With a 3.7V Li-ion input (within its 2.5V to 10V range), the LT3572EUF#TRPBF boost converter steps up the battery voltage to the higher potential required by piezo actuators, typically 10V to 30V depending on actuator characteristics, while the integrated dual 500mA drivers deliver the necessary peak current pulses. This architecture eliminates discrete boost inductors and driver ICs, reducing the wearable's total solution size significantly.

How does current-mode PWM control in the LT3572EUF#TRPBF benefit piezo actuator drive accuracy?

Current-mode PWM control in the LT3572EUF#TRPBF enables cycle-by-cycle peak current limiting for the 900mA boost converter, providing inherent short-circuit protection and fast load transient response. For piezo actuation, this translates to precise charge delivery per PWM cycle, ensuring consistent haptic intensity across varying battery voltages from 2.5V to 10V and temperature conditions, which is critical for repeatable user feedback sensation.

What package does the LT3572EUF#TRPBF use and how does it impact thermal performance in handheld designs?

The LT3572EUF#TRPBF is packaged in a 20-lead QFN (S-PQCC-N20) with an exposed pad that improves thermal dissipation through the PCB. This exposed pad reduces junction-to-board thermal resistance compared to SOIC or TSSOP packages, allowing the IC to sustain the full 500mA dual driver and 900mA boost operation without external heatsinks in most handheld operating environments up to 85°C ambient.
