Frequently Asked Questions
What is the input voltage range of the TPS62237DRY?
The TPS62237DRY operates with an input voltage range of 2.05V minimum to 6V maximum, with a nominal input of 3.6V. This range covers single-cell lithium-ion batteries, USB power sources (5V), and other portable supply voltages commonly used in wearable and IoT device designs.
What control techniques does the TPS62237DRY use?
The TPS62237DRY employs hysteretic current-mode control as its primary technique, and also supports both PWM (Pulse Width Modulation) and PFM (Pulse Frequency Modulation) control modes. The device automatically transitions between PWM and PFM based on load conditions, maximizing efficiency at both heavy and light loads.
How small is the TPS62237DRY package?
The TPS62237DRY is housed in a 6-pin USON package measuring only 1mm x 1.5mm, making it one of the smallest step-down converter packages available. This ultra-compact size is ideal for wearable devices, hearing aids, and any application where board space is severely constrained.
What are the advantages of the hysteretic current-mode control in the TPS62237DRY?
Hysteretic current-mode control in the TPS62237DRY provides very fast transient response to load changes without requiring external compensation networks. This simplifies design, reduces component count, and ensures stable output voltage even during rapid load steps common in portable electronics with burst-mode wireless communications.
What is the typical application for the TPS62237DRY?
The TPS62237DRY is typically used to step down battery or USB voltage to a lower regulated voltage in portable devices such as wearables, wireless earbuds, IoT sensor nodes, and portable medical devices. Its combination of tiny footprint, wide input range, and automatic efficiency optimization makes it particularly well-suited for battery-powered applications where runtime and space are critical.
