The TPS62135 and TPS621351 are high efficiency and easy to use synchronous step-down
DC-DC converters, based on the DCS-Control™
Topology. The devices wide input voltage range of 3-V to 17-V makes it suitable for multi-cell
Li-Ion as well as 12-V intermediate supply rails. The devices provide 4-A continuous output
current. The TPS62135 automatically enters Power Save Mode at light loads to maintain high
efficiency across the whole load range. With that, the device is well suited for applications that
require connected standby performance, like ultra low power computers. With the MODE pin set to
low, the switching frequency of the device is adapted automatically based on the input and output
voltage. This technique is called Automatic Efficiency Enhancement (AEE™) and maintains high
conversion efficiency over the whole operation range. It provides a 1% output voltage accuracy in
PWM mode and therefore enables the design of a power supply with high output voltage
accuracy.
The device has a typical quiescent current of 18 µA. In shutdown mode the current is
typically 1 µA and the output is actively discharged for TPS62135 while the output voltage
discharge feature is disabled in TPS621351.
The TPS62135 is available as an adjustable version, packaged in a 3-mm x 2-mm VQFN
package.
