VIN (Pin 1): This is the power input pin where you supply the input voltage for the buck converter. It typically takes input voltage in the range of 2.95V to 6V. EN (Pin 2): The enable pin is used to turn the regulator on or off. Applying a logic high will enable the device, and a logic low will disable it. PGND (Pin 3): Power ground pin, which should be connected to the system ground for proper operation of the circuit. VOUT (Pin 4): This is the output voltage pin. It delivers the regulated voltage to the load. FB (Pin 5): The feedback pin is used to monitor the output voltage and control the voltage regulation. SW (Pin 6): The switch pin is where the inductor is connected. It is the main switching node of the buck converter. PG (Pin 7): Power good pin indicates whether the output voltage is within regulation or not. It provides a logic low signal when the output is not within range. NC (Pin 8): No connect. This pin is typically left unconnected or used for mechanical stability. ILIM (Pin 9): The current limiting pin, used to set the threshold for current limit in the converter. VOUT_SENSE (Pin 10): This pin provides the voltage sensing for the output voltage. NC (Pin 11): Another non-connected pin, often left floating or connected to ground. NC (Pin 12): A non-connected pin, also typically left floating. FB2 (Pin 13): An additional feedback pin used for more precise or multi-phase regulation. LATCH (Pin 14): Used for latching output voltage or other functions based on the regulator design. VOUT_SEL (Pin 15): This pin allows users to select the output voltage when paired with other external components or configured with an internal reference voltage. NC (Pin 16): Another non-connected pin that is unconnected or used for mechanical support.Circuit Principle Instructions:
The TLV62130ARGTR is a buck converter that efficiently steps down the input voltage to a lower, stable output voltage. It uses a pulse-width modulation (PWM) control scheme to maintain a stable output voltage. The SW pin is connected to the inductor, and the switching frequency is determined by the internal control circuitry. The feedback mechanism (via the FB pin) ensures that the output voltage stays within the set tolerance. A power-good (PG) signal indicates the operational status of the output voltage.20 FAQ for TLV62130ARGTR:
