The TPS62065-Q1, TPS62067-Q1, and TPS62067A-Q1 devices are highly-efficient, synchronous, step-down DC/DC converters. The device provides up to 2-A output current.

With an input voltage range of 2.9 V to 6 V the device is an excellent 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 and has a power save mode, while the TPS62067A-Q1 operates in fixed frequency PWM mode. In the shutdown mode, the current consumption is reduced to 5 µA and an internal circuit discharges the output capacitor. The TPS62065-Q1, TPS62067-Q1, and TPS62067A-Q1 devices are optimized for operation with a tiny 1-µH inductor and a small 10-µF output capacitor to achieve smallest design size and high regulation performance.

The new product, TPS628502-Q1, offers reduced BOM cost and size, higher efficiency and other features.
