Frequently Asked Questions
What input voltage range does the TPS562212DRLR support, and does it handle 12 V industrial bus rails?
The TPS562212DRLR accepts input voltages from 4.2 V to 18 V, with a nominal operating point of 12 V, covering standard industrial and telecom bus voltages. This range also handles 5 V USB power sources and 9 V adapter rails in a single compact SOT-23-8 design.
How does current-mode PWM control in the TPS562212DRLR benefit transient response compared to voltage-mode regulators?
Current-mode control adds an inner current feedback loop that inherently limits peak inductor current on every switching cycle, enabling a much faster load-transient response—typically settling within a few microseconds for a 100 mA step—compared to voltage-mode designs that rely solely on the slower voltage error amplifier.
What external components are required to set the output voltage of the TPS562212DRLR?
Output voltage is set by a resistor divider feeding the feedback pin, an input bypass capacitor of at least 10 µF, an output inductor in the 1 µH to 10 µH range, and an output capacitor of at least 22 µF. Internal compensation eliminates the need for an external compensation network, reducing the total BOM to around 5 passive components.
