FEATURES
● Four Integrated Regulators 350mA PWM Step-Down DC/DC 80mA Low Noise LDO 150mA Low Noise LDO 300mA Low Noise LDOGENERAL DESCRIPTION
The patent-pending REG1 is a fixed-frequency, current-mode PWM step-down DC/DC converter that is optimized for high efficiency and is capable of supplying up to 350mA output current. REG1’s output is available in a variety of factory-preset output voltage options, and an adjustable output voltage mode is also available. REG2, REG3, and REG4 are low noise, high PSRR linear regulators that are capable of supplying up to 80mA, 150mA, and 300mA, respectively. Finally, an I2C serial interface provides programmability for the DC/DC converters and LDOs. The ACT8352 is available in a tiny 3mm 3mm 16-pin Thin-QFN package that is just 0.75mm thin.● Independent Enable/Disable Control
