Frequently Asked Questions
What control method does the STBB2JAD-R switching regulator use?
The STBB2JAD-R uses current-mode pulse width modulation (PWM) control, which provides inherent cycle-by-cycle current limiting and faster transient response compared to voltage-mode control. This makes it well-suited for powering dynamic loads like application processors and wireless chipsets in mobile devices.
What is the input voltage range of the STBB2JAD-R and what supply is it optimized for?
The STBB2JAD-R accepts input voltages from 2.4V minimum to 5.5V maximum, with a nominal input of 3.6V. This range is specifically optimized for single-cell Li-ion batteries (typical discharge range 3.0V to 4.2V), making it a natural fit for battery-powered portable and wearable electronics.
What package does the STBB2JAD-R use and what is its pin count?
The STBB2JAD-R is packaged in a 20-ball flip-chip BGA (R-PBGA-B20), a very compact form factor that enables dense PCB layouts for miniaturized power management circuits. The flip-chip technology reduces parasitic inductance and improves thermal performance compared to wire-bond packages of similar size.
What applications is the STBB2JAD-R intended for?
The STBB2JAD-R is intended for mobile and portable applications such as smartphones, smart watches, fitness trackers, Bluetooth headsets, and IoT edge nodes. Its single-function switching regulator design with PWM current-mode control makes it suitable for generating regulated supply rails for RF transceivers, MCUs, and sensors from a Li-ion battery source.
