General Description

The RT6160A is a high-efficiency, single inductor, Advanced Constant On-Time (ACOT®) monolithicsynchronous Buck-Boost converter that can deliver up to 3A output current from 2.2V to 5.5V and well regulate to the digitally programmable output voltage from 2.025V to 5.2V, which is suitable for wide input supply range applications, regardless of input voltage is lower, higher than or even equal to the output voltage. The ACOT® control architecture features outstandingline/load transient response, seamless transition between buck and boost modes, provides stable operation with small ceramic output capacitors and without complicated external compensation.

The RT6160A features I2C interface, which allowsprogrammable output voltage, ultra-sonic mode control, soft-start slew-rate adjusted and device status monitoring. The target output voltage can also be switched through external VSEL pin to perform dynamically-voltage-scaling (DVS), and the ramp-up slew-rate and ramp mode of DVS can also be set by setting the related registers.

The RT6160A operates in automatic PFM and typical

A low quiescent current design that maintains high efficiency during light load operation. At higher loads, the device automatically switches to a 2.2MHz fixed frequency control, which is easily smoothed-out he switching ripple voltage by small package filtering elements. And the integrated low RDS(ON) power MOSFETs features excellent efficiency during heavy load conditions. In shutdown mode, the supply current is typically 0.1A, excellent in reducing power consumption. PFM mode can be disabled if fixed frequency is desired. The RT6160A is available in a small WL-CSP-15B 1.4x2.3 (BSC) package.
