General Description
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. 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 in the
device to minimize the quiescent current during the controller
shutdown. This feature provides power savings for energy
critical applications.
Applications
âºâº Portable electronic equipment
âºâº MEMS
âºâº Printers
In addition, a built-in timer is available to protect the internal
circuit and to 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.
