The TPS62933EVM evaluation module (EVM) is used to evaluate the TPS62933, a high-efficiency, easy-to-use synchronous buck converter, which provides 5 V at 3 A from 3.8-V to 30-V input. The TPS62933 is suited for systems powered from 5-V, 12-V, 19-V, 24-V power-bus rails. The EVM 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 the external compensation components over a wide range of output voltage and operation frequency. The pulse frequency modulation (PFM) mode maximizes the light load efficiency. The ULQ™ (ultra low quiescent) feature is extremely beneficial for long battery life time in low power operation. The switching frequency can be set by the configuration of RT pin in the range of 200-kHz to 2.2-MHz, which allows optimizing system efficiency, filtering size and bandwidth.
