SiP12506 Datasheet | Vishay

Product is End of Life 3/2014 Si P12506 Vishay Siliconix 1-MHz Boost Converter with OVP for White LED Applications DESCRIPTION The Si P12506 is a 1 MHz current-mode boost converter with a feedback voltage of 0.208 V which offers small size and high power conversion efficiency. Its input voltage range is from 2.6 V to 9 V, and output voltage can go up to 20 V. The internal frequency pensation minimizes number of external ponents. The integrated 28 V power switch can carry up to 1.6 A easily providing for 200 m A load current from a 3.6 V input supply. These Features make the Si P12506 the ideal. The internal soft-start circuit controls the rate of rise of the output voltage during start-up to prevent overshoot. The logic-level shutdown pin can be used to reduce quiescent current to < 1 µA and, effectively, extend battery life. Thermal shutdown at 160 °C is also included. The low FB voltage of 0.208 V improves the overall circuit efficiency. These Features and more, make the Si...
