TI TPS62065QDSGRQ1

The TPS62065-Q1 and TPS62067-Q1 device is a highly-efficient synchronous step-down DC-DC converter. The device provides up to 2-A output current. With an input voltage range of 2.9 V to 6 V the device is a perfect fit for power conversion from a 5-V or 3.3-V system supply rail. The TPS62065-Q1 and TPS62067-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. The power save mode is optimized for low output-voltage ripple. For low noise applications, the TPS62065-Q1 device can be forced into fixed frequency PWM mode by pulling the MODE pin high. The TPS62067-Q1 provides an open drain power good output. In the shutdown mode, the current consumption is reduced to 5 μA and an internal circuit discharges the output capacitor. The TPS62065-Q1 and TPS62067-Q1 device is optimized for operation with a tiny 1-μH inductor and a small 10-μF output capacitor to achieve smallest solution size and high regulation performance. The TPS62065-Q1 and TPS62067-Q1 device is available in a small 2 × 2 × 0.75-mm 8 -pin WSON package.
