RT5785A - Synchronous Step-Down Converter

General Description

The RT5785A/B is a high-performance, Advanced Constant On-Time (ACOTTM) monolithic synchronous step-down DC-DC converter that can deliver up to 2A output current from a 2.5V to 6V input supply.

Key Features

  • quick transient response and provides stable operation with small ceramic output capacitors and without complicated external compensation. The switching ripple voltage is easily smoothed.
  • out by small package filtering elements due to a constant switching frequency of 1.5MHz and the maximum duty cycle of 100% allows the device to operate at low dropout use. With internal low on-resistance power switches and extremely low quiescent current, the RT5785A/B displays excellent efficiency and g.

® RT5785A/B 2A, 6V, 1.5MHz, 25μA IQ, ACOTTM Synchronous Step-Down Converter General Description The RT5785A/B is a high-performance, Advanced Constant On-Time (ACOTTM) monolithic synchronous step-down DC-DC converter that can deliver up to 2A output current from a 2.5V to 6V input supply. The proprietary ACOT control architecture features quick transient response and provides stable operation with small ceramic output capacitors and without complicated external compensation. The switching ripple voltage is easily smoothed–out by small package filtering elements due to a constant switching frequency of 1.5MHz and the maximum duty cycle of 100% allows the device to operate at low dropout use.
