3 Description
The TLV62095 device is a high frequency
synchronous step-down converter optimized for small
solution size, high efficiency and suitable for battery
powered applications. To maximize efficiency, the
converter operates in PWM mode with a nominal
switching frequency of 1.4MHz and it automatically
enters Power Save Mode operation at light load
currents. When used in distributed power supplies
and point of load regulation, the device allows voltage
tracking to other voltage rails and tolerates output
capacitors ranging from 10 µF to 150 µF and beyond.
Using the DCS-Control™ topology, the device
achieves excellent load transient performance and
accurate output voltage regulation.
The output voltage start-up ramp is controlled by the
soft startup pin, which allows operation as either a
standalone power supply or in tracking configurations.
Power sequencing is also possible by configuring the
EN and PG pins. In Power Save Mode, the device
operates with typically 20-µA quiescent current.
Power Save Mode is entered automatically and
seamlessly maintaining high efficiency over the entire
load current range.
The device is available in a 3 mm x 3 mm 16-pin
VQFN package.
