Allegro MicroSystems Inc. Automotive 2.4 Mhz. 2 A Buck Regulator Low Lq A8589KLPTR-T

Description
Designed to provide the power supply requirements of next generation car audio and infotainment systems, the A8589 provides all the control and protection circuitry to produce a high current regulator with ±1.0% output voltage accuracy. The A8589 employs pulse frequency modulation (PFM) to draw less than 50 μA from 12 VIN while supplying 3.3 V/40 μA. After startup, the A8589 operates down to at least 3.6 VIN (VIN falling). Features of the A8589 include a PWM/PFMn mode control input to enable PWM (logic high) or PFM (logic low). If the PWM/PFMn input is driven by an external clock signal higher than the base frequency ( fOSC) the PWM frequency synchronizes to the incoming clock frequency. The SLEEPn input pin commands an ultra-low current shutdown mode requiring less than 5 μA for internal circuitry and 10 μA (max) for MOSFET leakage at 16 VIN, 85ºC. The A8589 has external compensation to accommodate a wide range of frequencies and external components, and provides a power-on reset (NPOR) signal validated by the output voltage. Extensive protection features of the A8589 include pulse-by-pulse current limit, hiccup mode short circuit protection, open/short asynchronous diode protection, BOOT open/short voltage protection, VIN undervoltage lockout, VOUT overvoltage protection and thermal shutdown. The A8589 is supplied in a low profile 16-pin TSSOP package with exposed power pad (suffix LP). It is lead (Pb) free, with 100% matte-tin leadframe plating.
