DC / DC step-down converter controller
STMicroelectronics
The input voltage can range from 4.5 V to 28 V, while the output voltage can be set starting from 0.6 V to VIN.
Requiring a minimum set of external components, the device includes an internal 250 kHz switching frequency oscillator that can be externally adjusted up to 1 MHz.
The QFN and the HSOP packages with exposed pad allow reducing the RthJA down to 60°C/W and 40°C/W respectively.
