The TPS84620 integrated power solution is designed to provide up to a 6-A output. The TPS84620 contains dual-voltage inputs for the power stage and control circuitry. The power stage input (PVIN) is rated for 1.6 V to 14.5 V whereas the control input (VIN) is rated for 4.5 V to 14.5 V. The TPS84620EVM-692 provides both inputs but is designed and tested with PVIN connected to VIN.
This evaluation module is designed to demonstrate the small printed-circuit-board areas that may be achieved when designing with the TPS84620 regulator. The TPS84620EVM-692 default output voltage is 3.3 V at a 630-kHz switching frequency. The high-side and low-side MOSFETs are incorporated inside the TPS84620 package along with the gate drive circuitry. The low drain-to-source on-resistance of the MOSFET allows the TPS84620 to achieve high efficiencies and helps keep the junction temperature low at high output currents.
The compensation components are internal to the TPS84620, and external resistors and jumpers allow for adjustable output voltage and frequency adjustment. Additionally, the TPS84620 provides adjustable slow start, tracking, and undervoltage lockout inputs. The absolute maximum input voltage is 15 V for the TPS84620EVM-692.
