Motor vehicle control system of the electric motor is generally a power converter, electric vehicles, and the sensor controller, electric vehicle controller chip is used to control the motor to start the electric vehicle run, forward and backward, the speed, the electric vehicle is stopped and other electronic the core of the device control means, the electric vehicle is an important component, microelectronic Li Release PN6005 electric vehicle controller chip DC-DC buck chip. 
PN6005 DC-DC step-down electric vehicle controller chip integrated chip controllers and 200V PFM high avalanche intelligent power MOSFET, a very streamlined external components for low power non-isolated power switch.
PN6005 DC-DC buck controller ASIC chip built-in electric vehicles starting with a high pressure from the 200V power supply module, the system to achieve quick start, low standby, self-powered function. The chip provides a complete intelligent protection features including overload protection, undervoltage protection, over temperature protection, in addition PN6005 down-modulation technology can help improve EMI characteristics. 
PN6005 DC-DC buck chips features:
■ High Built 200V Smart Power avalanche the MOSFET
■ A high-voltage power supply circuit from the start and
■ for Buck, Buck-Boost, Flyback other architectures
■ fixed output voltage is 5V
■ SOP- 7 semi-closed steady state output current 36VDC @ 300mA
