The PSA/PSR Series of positive switching regulators are designed as power supplies for electronic systems when no input-to-output isolation is required. Their major advantages include a high level of efficiency, high reliability, low output ripple, and excellent dynamic response. Models with input voltages up to 144V are especially designed for secondary-switched and battery-driven mobile applications. Input voltage up to 144 VDC Single output of 5 to 48 VDC No input-to-output isolation High efficiency up to 95% Extremely wide input voltage range Low input-to-output differential voltage Very good dynamic properties Input undervoltage lockout Output voltage adjustment and inhibit function
