The TPS54290, TPS54291, and TPS54292 devices are dual-output, fully synchronous buck converters capable of supporting applications with a minimal numb.
Features
* 1 4.5-V to 18-V Input Range
* Output Voltage Range 0.8 V to DMAX × VIN
* Fully Integrated Dual Buck: 1.5 A and 2.5 A
* Three Fixed Switching Frequency Versions:
* TPS54290: 300 kHz
* TPS54291: 600 kHz
* TPS54292: 1.2 MHz
* Integrated U
Applications
* with a minimal number of external components. It operates from a 4.5-V to 18-V input supply voltage, and supports output voltages as low as 0.8 V and as high as 90% of the input voltage. Both high-side and low-side MOSFETs are integrated to provide fully synchronous conversion with higher efficiency
