Description

The EL7535IY is a type of synchronous, combined FET 350mA stepdown regulator in a MSOP10 package. The regulat or is internally compensated, which makes it suitable to utilize just five tiny external components to form a complete DC/DC converter. The regulator operates with an input voltage range from 2.5V to 6V, 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 divide r.The EL7535IYZ features PWM mode control. The operating frequency is typically 1.4MHz.

Features of the EL7535IY are:(1)extremely small 350mA DC/DC converter;(2)max height 1.1mm MSOP10 package;(3)possibly uses only five tiny external components with fixed output;(4)power-on-reset output (POR);(5)internally-co mpensated voltage mode controller;(6)up to 94% efficiency;(7)<1uA shut-down current;(8)overcurrent and over-te mperature protection;(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  EL7535IY can be summarized as:(1):VIN, VDD, POR to SGND: -0.3V to +6.5V;(2):LX to PGN D 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 500mA;(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 +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 6V max;(4):current limit is 1.5 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.
