This non-isolated design supplies an adjustable output voltage between -150 V and -250 V at 10 mA for LIDAR applications. It operates over an automotive input voltage range of 6 V to 40 V and accepts a control voltage from 0 V to 3 V for output voltage adjustment. Using a single inductor and operating in discontinuous conduction mode (DCM), this converter reference design offers a compact form factor and low cost.
