HV9150K6-G Microchip

HV9150 High-Voltage Output Hysteretic-Mode Step-Up DC/DC Controller Features General Description 6V to 500V Wide Output Voltage Range The HV9150 is a high output voltage Hysteretic mode step-up DC/DC controller that has a built-in charge 2.7V Low Input Voltage pump converter and a linear regulator for a wide range 5W Maximum Output Power with External of input voltage. The Charge Pump Converter mode is MOSFET Driver ideal for battery-powered applications. The internal Built-in Charge Pump Converter for the Gate converter can provide a minimum of 5V gate driver Driver output voltage (at V = 2.7V) to the external N-channel IN Programmable Switching Frequency from 40 kHz MOSFET. The range of 2.7V to 4.5V input supply to 400 kHz voltage is ideal for battery-powered applications, such Four Programmable Duty Cycles from 50% to as portable electronic equipment. The internal linear 87.5% regulator is selected when a higher supply voltage rail is available in the system. FB Return Ground Switch for Power-Saving Applications A feedback return ground path switch is also integrated Built-In Delay Timer for Internal Protection into the device to minimize the quiescent current during the controller shutdown. This feature provides power Non-Isolated DC/DC Converter savings for energy-critical applications. Applications In addition, a built-in timer is available to protect the internal circuit and help dissipate the energy from the Portable Electronic Equipment external high-voltage storage capacitor. This device is MEMS designed for systems requiring high-voltage and Printers low-current applications such as MEMS devices.
