Texas Instruments  TLV620612TDSGRQ1

The TLV620612-Q1 device is a highly efficient, synchronous step-down, DC-DC converter with a
1.2-V fixed output voltage. The device provides up to 1.6 A of output current.

With an input voltage range of 2.9 to 5.5 V, the device is a perfect fit for power conversion from a 5-V or 3.3-V system supply rail. The TLV620612-Q1 device operates at 3-MHz fixed frequency and enters power-save mode operation at light-load currents to maintain high efficiency over the entire load current range. For low-noise applications, the TLV620612-Q1 device can be forced into fixed-frequency PWM mode by pulling the MODE pin high.

In shutdown mode, the current consumption is reduced to less than 1 µA and an internal circuit discharges the output capacitor.

The TLV620612-Q1 device uses minimal board space by being available in a convenient 8-pin WSON package and operating with a small inductor (1 µH, typical) and output capacitor (10 µF, typical).

For all available packages, see the orderable addendum at the end of the datasheet.
