open-in-new Find other Buck converters (integrated switch)

Description

The TLV62065-Q1 device is a highly-efficient synchronous step-down DC-DC converter with adjustable output voltage. The device operates at a switching frequency of 3 MHz and provides up to 2 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 TLV62065-Q1 device enters power-save mode operation at light-load currents to maintain high efficiency over the entire load current range. For low-noise applications, the TLV62065-Q1 device can be forced into fixed-frequency PWM mode by pulling the MODE pin high.

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

The TLV62065-Q1 device operates with a 1-µH inductor and 10-µF output capacitor.

The TLV62065-Q1 device is available in a small
2-mm × 2-mm × 0.75-mm 8-pin WSON package.

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