ADP2118

The ADP2118 is designed as one kind of 3 A, 1.2 MHz/600 kHz high efficiency synchronous step-down DC-to-DC regulator device that can be used in wide range of applications such as (1)Point of load conversion; (2)Communications and networking equipments; (3)Industrial and instrumentation; (4)Consumer electronics; (5)Medical appliances. Also this device can be set to operate in pulse skip mode for higher efficiency or in forced PWM mode to reduce EMI.

Features of the ADP2118 are:(1)±1.5% output accuracy; (2)Input voltage range from 2.3 V to 5.5 V; (3)Output voltage from 0.6 V to VIN; (4)600 kHz or 1.2 MHz fixed switching frequency; (5)Synchronizable between 600 kHz and 1.4 MHz; (6)Selectable synchronize phase shift: 0o or 180o; (7)Selectable PWM or PFM mode operation; (8)Current mode architecture; (9)Precision enable input; (10)Power good output; (11)Voltage tracking input; (12)Integrated soft start; (13)Internal compensation; (14)Starts up into a precharged output; (15)UVLO, OVP, OCP, and thermal shutdown; (16)Available in 16-lead 4mm × 4mm LFCSP_WQ package.

The absolute maximum ratings of the ADP2118 can be summarized as:(1)Soldering Conditions: JEDEC J-STD-020;(2)PGND to GND: -0.3 V to +0.3 V;(3)Storage Temperature Range: -65°C to +150°C;(4)Operating Junction Temperature Range: -40°C to +125°C;(5)FB, SYNC/MODE, EN, TRK, FREQ, PGOOD: -0.3 V to +6 V;(6)SW: -0.3 V to +6 V.etc. If you want to know more information about the ADP2118, please download the datasheet in www.seekic.com or www.chinaicmart.com .
