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.

PMP8903 — 汽车类 SEPIC 转换器提供 4.5V@5.5A

In today’s start-stop systems, it is common for battery voltages to dip well below the nominal 12V rating. PMP8903 represents a very common start-stop application where that battery voltage can drop as low as 5V, and a 5V output is still needed for CAN and also as an intermediate bus. This (...)
