Frequently Asked Questions
What is the input voltage range of the TPS62085RLTT?
The TPS62085RLTT operates from an input voltage between 2.5V and 6V, with a nominal input of 3.6V. This range makes it compatible with single-cell lithium-ion or lithium-polymer batteries, USB power sources (5V), and 3.3V regulated bus supplies commonly found in portable and IoT device designs.
What output voltage can the TPS62085RLTT produce?
The TPS62085RLTT supports an adjustable output voltage from 0.8V to 6V, set via an external resistor divider. This wide output range allows a single part to cover processor core rails, memory supplies, RF power rails, and analog reference voltages across a variety of battery-powered and USB-connected embedded system designs.
How does the TPS62085RLTT achieve high efficiency at light loads?
The TPS62085RLTT automatically switches from PWM to PFM (Pulse Frequency Modulation) control at light loads. In PFM mode, the converter skips switching pulses when not needed, dramatically reducing switching losses and quiescent current consumption, which extends battery runtime in standby-heavy applications like wearables and IoT sensors.
What package does the TPS62085RLTT use?
The TPS62085RLTT is packaged in a 7-pin WSON (Wafer-level Small Outline No-lead) surface-mount package with JESD-30 code S-PDSO-N7. This ultra-compact, leadless package minimizes PCB area and supports the fine-pitch automated assembly processes required in high-density portable electronics and wearable device manufacturing.
What are typical applications for the TPS62085RLTT?
Typical applications include point-of-load regulators in smartphones, fitness bands, wireless earbuds, IoT sensor nodes, and medical wearables. The converter's combination of wide input/output range, PFM light-load efficiency, and miniature package also makes it suitable for industrial handheld instruments, USB accessories, and embedded modules where battery life and PCB space are critical constraints.
