The HV9150 is a high output voltage hysteretic mode step up DC/DC controller that has both a built-in charge pump converter and a linear regulator for a wide range of input voltage. The charge pump converter mode is ideal for battery powered applications. The internal converter can provide a minimum of 5.0V gate driver output voltage (at VIN = 2.7V) to the external N-channel MOSFET. The range of 2.7V to 4.5V input supply voltage is ideal for battery powered applications such as portable electronics equipment.
