The HT1662D regulator is a wide input range,current mode, DC/DC converter which is capable of generating either positive or negative output voltages.It can be configured as either a boost,flyback,SEPIC or inverting converter.
The HT1662D built in N-channel power MOSFET and fixed frequency oscillator, current-mode architecture results in stable operation over a wide range of supply and output voltages.
The HT1662D regulator is special design for portable electronic equipment.
