Description

General part information

ST2S08B Series

The ST2S08B is a dual step-down DC-DC converter optimized for powering low-voltage digital cores in ODD applications and, generally, to replace the high current linear solution when the power dissipation may cause a high heating of the application environment. It provides up to 1.5 A over an input voltage range of 3 V to 5.5 V. A high switching frequency of 1.5 MHz allows the use of tiny surface-mounted components as well as a resistor divider to set the output voltage value. Only an inductor and two capacitors are required. A low output ripple is guaranteed by the current mode PWM topology and the utilization of low ESR SMD ceramic capacitors. The device is thermally protected and current limited. The ST2S08B is available in the QFN12L (4 x 4 mm) package.
