The TPS6267x devices are high-frequency synchronous step-down dc-dc converters optimized
for small battery-powered applications. Intended for low-power applications, the TPS6267x supports
up to 650-mA load current and allows the use of low cost chip inductor and capacitors.
With a wide input voltage range of 2.3V to 4.8V, the device supports applications powered
by Li-Ion batteries with extended voltage range. Different fixed voltage output versions are
available from 1.05V to 2.1V. The TPS6267x operates at a regulated 6-MHz switching frequency and
enters the power-save mode operation at light load currents to maintain high efficiency over the
entire load current range.
The PFM mode extends the battery life by reducing the quiescent current to 17µA (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.
