Applications
The TPS62A02DRLR is designed for battery-powered portable electronics such as smartphones, wearables, and IoT nodes where efficient step-down conversion from a single-cell Li-ion supply is critical. Its PSM mode reduces switching losses at light loads, extending battery life in standby-heavy applications. It also suits point-of-load regulation on low-power microcontroller boards operating from a 3.3 V or 5 V bus.

Frequently Asked Questions
What is the input voltage range supported by the TPS62A02DRLR and what output current can it supply?
The TPS62A02DRLR accepts an input voltage between 2.5 V and 5.5 V, covering single-cell Li-ion and regulated 5 V rails. It can deliver a continuous output current up to 600 mA, making it suitable for powering low-power microcontrollers, wireless modules, and sensor nodes from a compact 6-pin SOT-23 package.
How does PSM mode in TPS62A02DRLR extend battery runtime in IoT designs?
In Power-Save Mode, the TPS62A02DRLR reduces switching frequency at light loads below approximately 100 mA, cutting switching losses and maintaining efficiency above 80% even at standby currents. For an IoT sensor that spends most of its time in sleep at under 10 mA, PSM can extend battery life by 2x or more compared to a fixed-frequency PWM-only converter.
When would a designer choose TPS62A02DRLR over a larger buck converter for a wearable device?
The SOT-23 6-pin package occupies roughly 8 mm² of board area, far less than SO-8 alternatives. When a wearable PCB has fewer than 200 mm² of available area and load current stays below 600 mA, the TPS62A02DRLR provides an integrated solution with internal compensation, reducing external component count to as few as 3 passives and shrinking total solution size significantly.
