The EL7536IYZ is a type of synchronous, combined FET 1A step-down regulator with internal compensation. It oper ates with an input voltage range from 2.5V to 5.5V, which accommodates supplies of 3.3V, 5V, or a Li-Ion battery so urce. The output is able to be externally set from 0.8V to VIN with a resistive divider.The EL7536IYZ features PWM mode control. The operating frequency is typically 1.4MHz.
Features of the EL7536IYZ are:(1)less than 0.15in2 (0.97cm2) footprint for the complete 1A converter; (2)componen ts on one side of PCB; (3)max height 1.1mm MSOP10; (4)100ms power-on-reset output (POR); (5)Internally-compe nsated voltage mode controller; (6)up to 94% efficiency; (7)<1uA shut-down current; (8)overcurrent and over-temp erature protection; (9)pb-free plus anneal available (RoHS compliant)
The absolute maximum ratings and electrical specifications(VDD = VIN = VEN = 3.3V, C1 = C2 = 10F, L = 1.8H, VO = 1.8V) of the EL7536IYZ can be summarized as:(1):VIN, VDD, POR to SGND: -0.3V to +6.5V;(2):LX to PGND is -0.3V to (VIN + +0.3V);(3):RSI, EN, VO, FB to SGND: -0.3V to (VIN + +0.3V);(4):PGND to SGND is-0.3V to +0.3V; (5):peak o utput current is 1.2A;(6):operating ambient temperature ranges from-40°C to +85°C;(7):storage temperature rang es from -65°C to +150°C;(8):junction temperature is +145°C.Electrical specifications:(1):feedback input voltage is 790mV min,800mV typ and 810mV max;(2):feedback input current is 250 nA max;(3): input voltage is 2.5V min and 5.5V max;(4):current limit is 1.5 A typ;(5):minimum RSI pulse width is 25nS typ and 50ns max when guaranteed by design;(6):soft-start time is 650us typ,etc.
