The TPS62933 is a high-efficiency, easy-to-use synchronous buck converter with a wide input voltage range of 3.8 V to 30 V, and supports up to 3-A continuous output current and 0.8-V to 22-V output voltage.

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 Ultra Low Quiescent (ULQ) feature is extremely beneficial for long battery lifetime in low-power operation. The switching frequency can be set by the configuration of the RT pin in the range of 200 kHz to 2.2 MHz, which allows the user to optimize system efficiency, filtering size, and bandwidth. The soft-start time can be adjusted by the external capacitor at the SS pin, which can minimize the inrush current when driving large capacitive load. This device also has the frequency spread spectrum feature, which helps in lowering EMI noise.

The device provides complete protections including OTP, OVP, UVLO, cycle-by-cycle OC limit, and UVP with Hiccup mode. This device is in a small SOT583 (1.6 mm × 2.1 mm) package with 0.5-mm pin pitch, and has an optimized pin-out for easy PCB layout and promotes good EMI performance.
