Texas Instruments TLV62065-Q1

Beschreibung

The TLV62065-Q1 is a highly efficient, synchronous step-down, dc-dc converter with a 1.2-V fixed output voltage.. It provides up to 2 A of output current.

With an input voltage range of 2.9 V 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-Q1operates at 3-MHz fixed frequency and enters powersave mode operation at light load currents to maintain high efficiency over the entire load current range. For low-noise applications, the TLV62065-Q1 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 operates with a 1-µH inductor and 10-µF output capacitor.The TLV62065-Q1 is available in a small 2-mm × 2-mm × 0.75-mm 8-pin SON package.
