Description

The EL7531IYZ is a type of synchronous, combined FET 1A step-down regulator with internal compensation. It opera es with an input voltage range from 2.5V to 5.5V, which accommodates supplies of 3.3V, 5V, or a Li-Ion battery sour e. The output is able to be externally set from 0.8V to VIN with a resistive divider.The EL7531IYZ features automatic PFM/PWM mode control, or PWM mode only. The PWM frequency is typically 1.4MHz and is able to be synchronized reach to 12MHz. The typical no load quiescent current is only 120A.

Features of the EL7531IYZ are:(1)less than 0.15 in2 (0.97 cm2) footprint for the complete 1A converter; (2)compone ts on one side of PCB; (3)max height 1.1mm MSOP10; (4)power-good (PG) output; (5)internally-compensated volt ge mode controller; (6)<1uA shut-down current;(7)overcurrent and over-temperature protection; (8)external synchroniz ble up to 12MHz; (9)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  EL7531IYZ can be summarized as:(1):VIN, VDD, POR to SGND: -0.3V to +6.5V;(2):LX to PG D is -0.3V to (VIN + +0.3V);(3):SYNC, 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 1.2A;(6):operating ambient temperature ranges from-40°C to +85°C;(7):storage temp rature ranges from -65°C to +150°C;(8):junction temperature is +125°C.Electrical specifications:(1):feed ack input voltage is 790mV min,800mV typ and 810mV max of PWM mode;(2):feedback input current is 100 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 min when  guaran eed by design;(6):soft-start time is 650us typ;(7):PWM switching frequency is 1.25MHz min, 1.4MHz typ and 1.6MHz max, etc.
