The TPS5420DR also comes in an 8-pin SOIC package, which is conducive for space-constrained designs. Its robust protection features and high efficiency make it ideal for applications in industrial power systems, communication equipment, and distributed power architectures.
Pinout
The TPS5420DR comes in an 8-pin SOIC (Small Outline Integrated Circuit) package. Below is a brief overview of its pin functions:
1. Vin: Input voltage supply.
2. GND: Ground reference for the device.
3. EN: Enable terminal which, when connected to a high logic level, enables the device.
4. SS/SD: Soft start and shutdown control. A capacitor connected to this pin sets the soft-start timing.
5. VSENSE: Feedback pin used to sense the output voltage for regulation.
6. COMP: Compensation node for stabilizing the control loop.
7. BOOT: Boost capacitor connection pin which provides a voltage higher than Vin to drive the high-side FET.
8. PH (Phase): Switch node for the inductor connection.
These pins collectively support the TPS5420DR’s function to efficiently step down DC voltages, driving loads with currents up to 2 A.
