PRODUCT NAME: 10PCS/LOT 1.2MHZ Step-up DC/DC Converter in SOT23-6  XR1151  MARK B628 BOOST CONVERTER

GENERAL DESCRIPTION    

The XR1151 step-up switching regulator generates an output voltage of up to 6V from an input voltage as low as 1.6V. Ideal for applications where space is limited, it switches at 1.2MHz, allowing the use of tiny, low cost and low profile external components. Its internal 2A, 100mΩ NMOS switch provides high efficiency even at heavy load, while the constant frequency, current mode architecture results in low, predictable output noise that is easy to filter. Internal frequency compensation is designed to accommodate ceramic output capacitors, further reducing noise. The device features very low shutdown current of 0.5uA.   The XR1151  is available in the 6-lead SOT-23 package.
