Description:

The TLV62065-Q1 is a high-efficiency, synchronous step-down DC-DC converter with a fixed 1.2-V output voltage. It provides up to 2A of output current. With an input voltage range of 2.9V to 5.5V, this device is ideal for power conversion from 5-V or 3.3-V system supply rails. The TLV62065-Q1 operates at a fixed frequency of 3 MHz and enters power save mode at light load currents to maintain high efficiency across 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 shutdown mode, current consumption is reduced to less than 1µA, and an internal circuit discharges the output capacitor. The TLV62065-Q1 operates with a 1-µH inductor and a 10-µF output capacitor. The device is available in a 2-mm × 2-mm × 0.75-mm 8-pin SON package.
