The TPS6293x 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 2-A (TPS62932) and 3-A (TPS62933 and TPS62933x) 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.

The TPS62932, TPS62933, and TPS62933P operate in pulse frequency modulation for high light load efficiency. The TPS62933F operates in forced continuous current modulation which maintains lower output ripple during all load conditions. The TPS62933O operates in out of audio mode to avoid audible noise.

The ULQ (ultra-low quiescent) feature is beneficial for long battery lifetime. The switching frequency can be set by the configuration of the RT pin in the range of 200 kHz to 2.2 MHz, which can optimize system efficiency, solution size, and bandwidth. The soft-start time of the TPS62932, TPS62933, and TPS62933F can be adjusted by the external capacitor at the SS pin. The TPS62932, TPS62933, TPS62933P and TPS62933O are featured with frequency spread spectrum, which helps with lowering down EMI noise.

The TPS6293x is in a small SOT583 (1.6 mm × 2.1 mm) package with 0.5-mm pin pitch, and has an optimized pinout for easy PCB layout and promotes good EMI performance.
