Product Summary
The ST1S09IPUR is a step-down DC-DC converter optimized for powering low output voltage applications. It supplies a current in excess of 2 A over an input voltage range from 2.7 V to 6 V. A high PWM switching frequency (1.5 MHz) allows the use of tiny surface-mount components.
Parametrics
ST1S09IPUR absolute maximum ratings: (1)Positive power supply voltage: -0.3 to 7 V; (2)Positive power supply voltage: -0.3 to 7 V; (3)Inhibit voltage (I version): -0.3 to VI + 0.3 V; (4)Max. voltage of output pin: -0.3 to 7 V; (5)Feedback voltage: -0.3 to 3 V; (6)Power Good open drain: -0.3 to 7 V; (7)Max junction temperature: -40 to 150 °C; (8)Storage temperature range: -65 to 150 °C; (9): Lead temperature (soldering): 10 sec 260 °C.
Features
ST1S09IPUR features: (1)1.5 MHz fixed frequency PWM with current control mode; (2)2 A output current capability; (3)Typical efficiency: > 90%; (4)2 % DC output voltage tolerance; (5)Two versions available: power good or inhibit; (6)Integrated output over-voltage protection; (7)Non switching quiescent current: (typ)1.5 mA over temperature range; (8)RDSON (typ)100 mΩ; (9)Utilizes tiny capacitors and inductors; (10)Operating junction temp. -30 °C to 125 °C; (11)Available in DFN6 (3 x 3 mm)exposed pad.
