Allegro MicroSystems Inc. Wide Input Voltage Adj Frequency 3.5A Buck Reg A8586KLJTR-T

Description
The A8586 is a high frequency step-down switching regulator with an integrated high-side power MOSFET. It provides up 3.5 A output current. The A8586 can achieve fast transient response utilizing current mode control and simple external compensation. The wide input range of 3.8 V to 36 V makes the A8586 suitable for a wide range of step-down applications, including those in an automotive input environment. Battery driven applications benefit from the low 30 μA operational quiescent current. The A8586 provides maintains high efficiency across a wide load range by the use of pulse frequency modulation (PFM) as the load reduces. This in turn reduces switching and gate driver losses at light load. A8586-1 and A8586-2 are options that disable the PFM function. A8586-1 also disables the dithering feature. These can be useful when low output ripple and minimum output capacitance is required. Frequency fold back helps prevent inductor current runaway during startup and provides enhanced dropout performance. Extensive protection features of the A8586 include pulse-by-pulse current limit, hiccup mode short circuit protection, open/ short freewheeling diode protection, BOOT open/short voltage protection, VIN undervoltage lockout, and thermal shutdown. The A8586 and A8586-2 are designed to aid in EMC/EMI design by including frequency dithering, soft freewheel diode turn off, and well controlled switch node slew rates. A 4 MHz oscillator allows the A8586 to switch outside EMI sensitive frequencies bands such as the AM band or ADSL bands. The A8586 is available in industry standard DFN10 or SOIC8 packages.
