LTC1515CS8#PBF, Регулируемый DC/DC преобразователь напряжения с подкачкой заряда, 2В до 10В, 2В до 10В/50мА, 650кГц

The LTC1515CS8#PBF is a step-up/down switched-capacitor DC/DC charge-pump Converter with reset. The converter produces a regulated output voltage by either stepping up or stepping down the input voltage. Output voltage is adjustable using an external resistor divider (LTC1515) or programmable to either 3/5V. A unique architecture allows the parts to accommodate a wide input voltage range (2 to 10V) while maintaining ±4% regulation. Additional circuitry prevents excessive inrush current and output voltage ripple when large VIN to VOUT differentials are present. An internal power-ON reset circuit forces the POR pin low on initial power-up. The POR output remains low until 200ms after VOUT is in regulation. The part is short-circuiting and over temperature protected. Battery life is maximized by very low operating currents.
