The TPS563900 is a dual output current mode control dc/dc converter with output rated for up to 3.5 A. The input voltage range is 4.5 V to 18 V. Rated input voltage and output current range for the evaluation module are given in Table 1-1. The TPS563900 features I²C VID control. The output voltage for each channel can be set within the range of 0.68 V to 1.95 V. This evaluation module is designed to demonstrate the small printed-circuit-board (PCB) areas that may be achieved when designing with the TPS563900 regulator. The switching frequency is externally set at a nominal 500 kHz. The high-side and low-side MOSFETs are incorporated inside the TPS563900 package along with the gate drive circuitry. The low drain-to-source on-resistance of the MOSFET allows the TPS563900 to achieve high efficiencies and helps keep the junction temperature low at high output currents. The compensation components are external to the integrated circuit (IC), and an external divider allows for an adjustable output voltage. Additionally, the TPS563900 provides adjustable slow start and undervoltage lockout inputs. The absolute maximum input voltage is 20 V for the TPS563900EVM-574.
