Analog Devices Inc. ADP2450 Power Management IC

Analog Devices ADP2450 Power Management IC is optimized for low-voltage circuit breakers, such as the molded case circuit breaker (MCCB), and current transformer-powered supply applications. The device integrates four low offset, low power consumption amplifiers. The ADP2450's programmable gain features provide accuracy measurement over a wide current input range based on the CT turn ratio. A low offset operation amplifier is integrated in the device for leakage current detection. The buck regulator operates over a wide input voltage range of 4.5V to 36V. The output voltage can be adjusted down to 0.6V. The buck regulator provides output currents of up to 500mA.
