Frequently Asked Questions
What is the input voltage range of the TPS62665YFFT?
The TPS62665YFFT operates over an input voltage range of 2.3V to 5.5V, with a nominal input of 3.6V. This makes it directly compatible with single-cell Li-ion or LiPo batteries commonly used in portable and wearable devices.
What control modes does the TPS62665YFFT support?
The TPS62665YFFT supports both Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) control techniques. PWM mode provides stable regulation under heavy loads, while PFM mode reduces switching losses at light loads, significantly improving battery life in low-power applications.
What package does the TPS62665YFFT come in?
The TPS62665YFFT uses a 6-ball Wafer-Level Chip-Scale Package (WLCSP), designated as R-PBGA-B6. This ultra-compact package is ideal for space-constrained PCB designs in wearables, hearables, and miniaturized IoT devices.
Is the TPS62665YFFT RoHS compliant?
Yes, the TPS62665YFFT is fully RoHS compliant and lead-free (Pb-free). Texas Instruments also provides an estimated time-to-end-of-life (YTEOL) of 15 years, ensuring long-term supply availability for production programs.
