3 Description
The TPSM82901 is a highly efficient, small, and
flexible synchronous step-down DC-DC converter
MicroSiP package module that is easy to use. A
selectable switching frequency of 2.5 MHz or 1.0 MHz
allows the use of small components and provides fast
transient response. The device supports high VOUT
accuracy of ± 1 with the DCS-Control topology. The
wide input voltage range of 3 V to 17 V supports a
variety of nominal inputs, like 12-V supply rails, singlecell
or multi-cell Li-Ion, and 5-V or 3.3-V rails.
The TPSM82901 can automatically enter power save
mode (if auto PFM/PWM is selected) at light loads to
maintain high efficiency. Additionally, to provide high
efficiency at very small loads, the device has a low
typical quiescent current of 4 μA. AEE, if enabled,
provides high efficiency across VIN, VOUT, and load
current. The device includes a MODE/Smart-CONF
input to set the internal/external divider, switching
frequency, output voltage discharge, and automatic
power save mode or forced PWM operation.
The device is available in small 11-pin MicroSiP
package measuring 3.0 mm × 2.8 mm × 1.6 mm with
an integrated 1-μH inductor.
