Description

The EL7532IYZ is a type of synchronous, combined FET 2A 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 single Li-Ion bat tery source. The output is able to be externally set from 0.8V to VIN with a resistive divider.The EL7532IYZ features PWM mode control. The operating frequency is typically 1.5MHz.

Features of the EL7532IYZ are:(1)2A continuous current (from -40 to +85); (2)less than 0.18 in2 footprint for the complete 2A converter; (3)max height 1.1mm MSOP10; (4)1.5MHz (typ.) switching frequency; (5)100ms power-on-re set output (POR); (6)internally-compensated voltage mode controller; (7)up to 94% efficiency; (8)<1uA shut-down cu rrent; (9)overcurrent and over temperature protection; (10)pb-free plus anneal available (RoHS compliant).

The absolute maximum ratings(TA=25°C) and electrical specifications(VDD = VIN = VEN = 3.3V, C1 = C2 = 10F, L = 1.8H, VO = 1.8V) of the  EL7532IYZ can be summarized as:(1):VIN, VDD, POR to SGND: -0.3V to +6.5V;(2):LX to PG ND 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 output current is 2.4A;(6):operating ambient temperature ranges from-40°C to +85°C;(7):storage temp erature ranges from -65°C to +150°C;(8):junction temperature is +125°C.Electrical specifications:(1):feedback in put 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 3 A typ;(5):minimum RSI pulse width is 25nS typ and 50ns max when  guar anteed by design;(6):soft-start time is 650us typ,etc.
