Description

The EL7530IYZ is a type of synchronous, combined FET 600mA stepdown regulator with internal compensation. It op erates with an input voltage range from 2.5V to 5.5V, which accommodates supplies of 3.3V, 5V, or a Li-Ion battery source. The output is able to be externally set from 0.8V to VIN with a resistive divider.The EL7530IYZ features auto matic PFM/PWM mode control, or PWM mode only. The PWM frequency is typically 1.4MHz and is able to be synchroni zed reach to 12MHz. The typical no load quiescent current is only 120A.

Features of the EL7530IYZ are:(1)less than 0.18in2 footprint for the complete 600mA converter; (2)components on one side of PCB; (3)max height 1.1mm MSOP10; (4)power-good (PG) output; (5)internally-compensated voltage mo de controller; (6)up to 95% efficiency; (7)<1uA shut-down current; (8)120uA quiescent current; (9)overcurrent and over-temperature protection; (10)external synchronizable up to 12MHz; (11)pb-free plus anneal available (RoHS com pliant).

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 EL7530IYZ 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):SYNC, EN, VO, FB to SGND: -0.3V to (VIN + +0.3V);(4):PGND to SGND is-0.3V to +0.3 V; (5):peak output current is 800mA;(6):operating ambient temperature ranges from-40°C to +85°C;(7):storage temperature ranges from -65°C to +150°C;(8):junction temperature is +125°C.Electrical specifications:(1):feedba ck 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 whe n  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.
