ST1S06
Synchronous rectification with inhibit, 1.5A, 1.5 MHz fixed or adjustable, step-down switching regulator in DFN6 3x3
General features

Step-down current mode PWM (1.5MHz) DCDC converter 2% DC output voltage tolerance Synchronous rectification Inhibit function Internal soft start Typical efficiency:> 90% 1.5A Output current capability Not switching quiescent current: max 1.5mA over temperature range RDS ON typ150m Uses tiny capacitors and inductors Operative junction temp. -30 C to 125 C Available in DFN6 3x3 exposed pad high current linear solution when the power dissipation may cause an high heating of the application environment. It provides up to 1.5A over an input voltage range of 2.7V to 6V. An high switching frequency (1.5MHz) allows the use of tiny surface-mount components: as well as the resistor divider to set the output voltage value, only an inductor and two capacitors are required. Besides, a low output ripple is guaranteed by the current mode PWM topology and by the use of low E.S.R. SMD ceramic capacitors. The device is thermal protected and current limited to prevent damages due to accidental short circuit. The ST1S06 is avai
lable in DFN6 3x3 package.
