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.
