Frequently Asked Questions

What is the input voltage range of the TPS62223DDCTG4?

The TPS62223DDCTG4 accepts input voltages from 2.5V to 6V, with a nominal operating point of 3.6V. This range covers single-cell lithium-ion batteries (2.7V–4.2V) and regulated 5V bus supplies, making it versatile for portable and embedded power management designs.

What control modes does the TPS62223DDCTG4 support?

The device supports both Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) modes. PWM mode provides a fixed switching frequency for clean EMI and good transient response at medium-to-heavy loads, while PFM mode reduces switching losses at light loads to extend battery runtime in sleep-mode IoT and portable applications.

How much output current can the TPS62223DDCTG4 supply?

The TPS62223DDCTG4 delivers up to 400mA of continuous output current. This capacity is sufficient to power microcontrollers, Bluetooth or Wi-Fi modules, sensor arrays, and small display drivers commonly found in wearable and handheld consumer electronics.

What package does the TPS62223DDCTG4 use?

The TPS62223DDCTG4 is housed in a 5-pin SOT-23 (DCT) surface-mount package. The small form factor makes it ideal for compact power rails on densely populated PCBs in portable devices, wireless sensors, and space-constrained embedded modules.

Does the TPS62223DDCTG4 require an external inductor and capacitors?

Yes, like most switching regulators the TPS62223DDCTG4 requires an external inductor (typically 2.2µH–4.7µH), an input bypass capacitor, and an output filter capacitor. Texas Instruments provides recommended component values in the datasheet to achieve stable operation across the full 2.5V–6V input range and 400mA load current.
