Product Summary
The 1269AS-H-1R0MP2 is a low input voltage step-up converter in thin SOT-23 package. The 1269AS-H-1R0MP2 provides a power-supply solution for products powered by either a single-cell, two-cell, or threecell alkaline, NiCd or NiMH, or one-cell Li-Ion or Li-polymer battery. Possible output currents depend on the input-to-output voltage ratio. The boost converter is based on a hysteretic controller topology using synchronous rectification to obtain maximum efficiency at minimal quiescent currents. The output voltage of the adjustable version can be programmed by an external resistor divider, or is set internally to a fixed output voltage. The 1269AS-H-1R0MP2 can be switched off by a featured enable pin. While being switched off, battery drain is minimized. The 1269AS-H-1R0MP2 is packaged in a 6-pin thin SOT-23 package (DBV). Applications are (1)Battery powered applications: 1 to 3 cell alkaline, NiCd or NiMH; 1 cell li-ion or li-primary; (2)Solar or fuel cell powered applications; (3)Consumer and portable medical products; (4)Personal care products; (5)White or status LEDs; (6)Smartphones.
