Description

The EL7530IY is a type of synchronous, combined FET 600mA stepdown regulator with internal compensation. It ope rates 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 EL7530IYZ features autom atic PFM/PWM mode control, or PWM mode only. The PWM frequency is typically 1.4MHz and is able to be synchronize d reach to 12MHz. The typical no load quiescent current is only 120A.

Features of the EL7530IY are:(1)less than 0.18in2 footprint for the complete 600mA converter; (2)components on on e side of PCB; (3)max height 1.1mm MSOP10; (4)power-good (PG) output; (5)internally-compensated voltage mode controller; (6)up to 95% efficiency; (7)<1uA shut-down current; (8)120uA quiescent current; (9)overcurrent and ove r-temperature protection; (10)external synchronizable up to 12MHz; (11)pb-free plus anneal available (RoHS complia nt).

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 EL7530IY 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):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 800mA;(6):operating ambient temperature ranges from-40°C to +85°C;(7):storage tem perature ranges from -65°C to +150°C;(8):junction temperature is +125°C.Electrical specifications:(1):feedback 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 1.2A typ;(5):minimum RSI pulse width is 25nS min when  guaranteed by design;(6):soft-start time is 650us typ,etc;(7):PWM switching frequency is 1.25MHz min,1.4MHz typ and 1.6MHz max.
