LN2351 Super-Small Package VFM Control Step-up Switching Regulator ■ General Description The LN2351 Series is a CMOS VFM-control step-up switching regulator that mainly consists of a reference voltage source, an oscillator, and a comparator. enabling products with a low ripple over a wide range, high efficiency, and high output current. Products with a fixed duty ratio of 75 % ( Lower Output Voltage ) or 88%(Higher Output Voltage) are also available. With the LN2351 Series, a step-up switching regulator can be configured by using an external coil, capacitor, and diode. A protection circuit turns off the built-in MOS FET when the voltage at the CONT pin exceeds the limit to prevent it from being damaged. This feature, along with the mini package and low current consumption, makes the LN2351 Series ideal for applications such as the power supply unit of portable equipment. ■ Features  Low voltage operation: Start up at 0.9 V min(IOUT=1 mA) guaranteed  Low input current: Du.
