The TPS82130 is a 17-V input 3-A step-down converter MicroSiP power module optimized for small solution size and high efficiency. The module integrates a synchronous step-down converter and an inductor to simplify design, reduce external components, and save PCB area. The low profile and compact solution is suitable for automated assembly by standard surface mount equipment.
To maximize
efficiency, the converter operates in PWM mode with a nominal switching frequency of
2 MHz and automatically enters power save mode
operation at light load currents. In power save mode, the device operates with 20-µA
(typical) quiescent current. Using the DCS-Control topology, the device achieves
excellent load transient performance and accurate output voltage
regulation.

PIN | I/O | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
EN | 1 | I | Enable pin. Pull High to enable the device. Pull Low to disable the device. This pin has an internal pulldown resistor of typically 400 kΩ when the device is disabled. |
VIN | 2 | PWR | Input pin |
GND | 3 | Ground pin | |
VOUT | 4, 5 | PWR | Output pin |
FB | 6 | I | Feedback reference pin. An external resistor divider connected to this pin programs the output voltage. |
PG | 7 | O | Power-good open-drain output pin. A pullup resistor can be connected to any voltage less than 6 V. Leave this pin open if it is not used. |
SS/TR | 8 | I | Soft start-up and voltage tracking pin. An external capacitor connected to this pin sets the internal reference voltage rising time. |
Exposed Thermal Pad | The exposed thermal pad must be connected to the GND pin. Must be soldered to achieve appropriate power dissipation and mechanical reliability. |
