MICROCHIP HV9150K6-G

A high output voltage Hysteretic mode step-up DC/DC controller that has 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 5V gate driver output voltage (at V_IN = 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 electronic equipment. The internal linear regulator is selected when a higher supply voltage rail is available in the system. A feedback return ground path switch is also integrated into the device to minimize the quiescent current during the controller shutdown. This feature provides power savings for energy-critical applications. In addition, a built-in timer is available to protect the internal circuit and help dissipate the energy from the external high-voltage storage capacitor. This device is designed for systems requiring high-voltage and low-current applications such as MEMS devices.
