3 Description

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.
