1 Introduction

The TPS563300 is a high efficiency, easy-to-use synchronous buck converter. With the wide input voltage range of 3.8 V to 28 V, the device is ideally suited for systems powered from 5-V, 12-V, 19-V, 24-V power-bus rails. The device supports up to 3-A continuous output current, 0.8-V to 22-V output voltage and maximum 98% duty cycle operation. The device employs fixed-frequency peak current control mode for fast transient response and good line and load regulation. The optimized internal loop compensation eliminates external compensation components over a wide range of output voltage and operation frequency. Pulse frequency modulation (PFM) mode maximizes the light load efficiency. The low quiescent current feature is beneficial for long battery life time in low-power operation. The device also has a frequency spread spectrum feature, which helps with lowering down EMI noise.

The TPS563300EVM evaluation module (EVM) is a single, synchronous buck converter providing 5 V at 3 A from 5.1-V to 28-V input. This user’s guide describes the TPS563300EVM performance. Rated input voltage and output current ranges for the evaluation module are given in Table 1-1.
