The ST1S03PUR is a step-down DC-to-DC Converter optimized for powering a low voltage digital core in HDD 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 1.5A over an input voltage range of 3 to 16V. A 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, a Schottky diode and two capacitors are required. Besides, a low output ripple is guaranteed by the current-mode PWM topology and by the use of low ESR SMD ceramic capacitors. The device is thermal protected and current limited to prevent damages due to an accidental short-circuit.
- Uses tiny capacitors and inductors
- Internal soft-start for startup current limitation and power on delay of 50 to 100µs
- Typical efficiency of 70% overall operating conditions
- 2% DC output voltage tolerance
- Maximum not switching quiescent current of 2.5mA over temperature range
- 350mV at ISW=750mA Maximum switch VDS
