Texas Instruments TPS62933P

Description

The TPS62933P is a high efficiency, easy-to-use synchronous buck converter. With the wide input voltage range of 3.8-V to 30-V, it is ideally suited for systems powered from 5-V, 12-V, 19-V, and 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 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) DC/DC converter 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.
