DESCRIPTION
31mA Quiescent Current
The
TPS6261x
device
is
a
high-frequency
Wide VIN Range From 2.3V to 5.5V
synchronous step-down dc-dc converter optimized for
6MHz Regulated Frequency Operation
battery-powered portable applications. Intended for
low-power applications, the TPS6261x supports up to
Best in Class Load and Line Transient
350-mA load current, and allows the use of low cost

chip inductor and capacitors.
Automatic PFM/PWM Mode Switching
With a wide input voltage range of 2.3V to 5.5V, the
Low Ripple Light-Load PFM Mode
device supports applications powered by Li-Ion
>50dB VIN PSRR (1kHz to 10kHz)
batteries with extended voltage range. Different fixed
voltage output versions are available from 1.2V to
Internal Soft-Start, 100-ms Start-Up Time
2.3V.
Integrated Active Power-Down Sequencing
(Optional)
The TPS6261x operates at a regulated 6-MHz
switching frequency and enters the power-save mode
