LM337 - Voltage Regulator - Adjustable Output, Negative
www.onsemi.comVoltage Regulator - Adjustable Output, Negative 1.5 A LM337 The LM337 is an adjustable 3−terminal negative voltage regulator capable of supplying in excess of 1.5 A over an output voltage range of −1.2 V to −37 V. This voltage regulator is exceptionally easy to use and requires only two external resistors to set the output voltage.
Creating a Negative Output Voltage Using a Buck Converter
www.vishay.comsynchronous buck converter, we can create a negative boost converter, as shown in Fig. 1. Fig. 1 This will suit applications that need to generate complimentary output voltages, such as audio, or industrial applications requiring negative voltage levels, such as IGBT gate drive turn-off. Other uses have been observed in LCD displays and
