XR-2525A Datasheet | Exar

DESCRIPTION The XR-1525A11527A is a series of monolithic integrated circuits that contain all of the control circuitry necessary for a pulse-width modulating regulator. Included in the 16-Pin dual-in-line package is a voltage reference, an error amplifier, a pulse-width modulator, an oscillator, under-voltage lockout, soft-start circuitry, and output drivers. FUNCTIONAL BLOCK DIAGRAM INV INPUT NON- Ir-;V INPUT SYNC The XR-1525A12525A13525A series features NOR logic, giving a LOW output for an OFF state. The XR-1527AI 2525A13527A series features OR logic, giving a HIGH output for an OFF state. FEATURES 8V to 35V Operation 5.1 V Reference Trimmed to ± 1% 100 Hz to 500 k Hz Oscillator Range Separate Oscillator Sync Terminal Adjustable Deadtime Control Internal Soft-Start Input Under-voltage Lockout Latching PWM to Prevent Double Pulsing Dual Source/Sink Output Drivers Capable of Over 200 m A Power-...
