36V,2.4A Monolithic Step-Down Switching Regulator

1、Features 2.4A continuous output current capability 6.5V to 36V wide operating input range with 33V input Over Voltage Protection Integrated 36V, 108mΩ high side and 36V, 102mΩ low side power MOSFET switches Up to 95% efficiency Internally fixed 3A constant current control Programmable Soft-Start limits the inrush current at turn-on Stable with Low ESR Ceramic Output Capacitors Fixed 500KHz Switching Frequency Input Under-Voltage Lockout. Output Over-VoltageProtection Over-Temperature Protection Thermally Enhanced ESOP-8 Package	2、Applications USB car charger Portable charging device General purpose DC-DC conversion 3、Description The PL83251 is a monolithic 36V, 2.4A step-down switching regulator with CC/CV control loop. PL83251 integrates a high efficiency synchronous step-down switching regulator, which includes a 36V 108mΩ high side and a 36V, 102mΩ low side MOSFETs to provide 2.4A continuous load current over a 6.5V to 36V wide operating input voltage. Peak current mode control provides fast transient responses and cycle-by-cycle current limiting.Programmable soft-start prevents inrush current at power-up. The supply current drops below 1μA in shutdown mode.
