DESCRIPTION
Low Ripple Light-Load PFM Mode
The
TPS6267x
device
is
a
high-frequency
synchronous step-down dc-dc converter optimized for
≥35dB VIN PSRR (1kHz to 10kHz)
battery-powered portable applications. Intended for
Simple Logic Enable Inputs
low-power applications, the TPS6267x supports up to
Supports External Clock Presence Detect
600-mA load current, and allows the use of low cost

chip inductor and capacitors.
Three Surface-Mount External Components
With a wide input voltage range of 2.3V to 4.8V, the
Required (One 0603 MLCC Inductor, Two 0402
device supports applications powered by Li-Ion
Ceramic Capacitors)
batteries with extended voltage range. Different fixed
voltage output versions are available from 1.0V to

efficiency over the entire load current range.
The PFM mode extends the battery life by reducing
the quiescent current to 17
μA (typ) during light load
operation. For noise-sensitive applications, the device
has PWM spread spectrum capability providing a
lower noise regulated output, as well as low noise at
the input. These features, combined with high PSRR
and AC load regulation performance, make this
device suitable to replace a linear regulator to obtain
better power conversion efficiency.
