Additional Infomation About Product

ST1S09 2 A, 1.5 MHz PWM step-down switching regulator with synchronous rectification Features 1.5 MHz fixed frequency PWM with current control mode 2 A output current capability Typical efficiency: > 90% 2 % DC output voltage tolerance Two versions available: power good or inhibit DFN6 (3 x 3 mm) Integrated output over-voltage protection Non switching quiescent current: (typ) 1.5 mA over temperature range R (typ) 100 m DSON Moreover, since the required synchronous Utilizes tiny capacitors and inductors rectifier is integrated, the number of the external Operating junction temp. -30 C to 125 C components is reduced to minimum: a resistor divider, an inductor and two capacitors. The Available in DFN6 (3 x 3 mm) exposed pad Power Good function continuously monitors the output voltage. An open drain Power Good flag is Description released when the output voltage is within regulation. In addition, a low output ripple is The ST1S09 is a step-down DC-DC converter guaranteed by the current mode PWM topology optimized for powering low output voltage and by the use of low ESR SMD ceramic applications. It supplies a current in excess of 2 A capacitors. The device is thermally protected and over an input voltage range from 2.7 V to 6 V. the output current limited to prevent damages due A high PWM switching frequency (1.5 MHz) to accidental short circuit. The ST1S09 is allows the use of tiny surface-mount components. available in the DFN6 (3 x 3 mm) package. Table 1.
