描述 Description

The TLV62065 device is a high efficiency synchronous step-down DC?DC converter. It provides up to 2-A 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 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, TLV62065 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.
TLV62065 operates with a 1-μH inductor and 10-μF output capacitor.
The TLV62065 is available in a small 2 mm × 2 mm × 0.75 mm 8-pin WSON package.
