ADP2119

The ADP2119 is designed as one kind of 2 A/1.25 A, 1.2 MHz, 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 ADP2119 are:(1)145 m and 70 m integrated MOSFETs; (2)Input voltage range from 2.3 V to 5.5 V; (3)Output voltage from 0.6 V to VIN; (4)±1.5% output accuracy; (5)1.2 MHz fixed switching frequency; (6)Synchronizable between 1 MHz and 2 MHz; (7)Selectable PWM or PFM mode operation; (8)Current mode architecture; (9)Precision threshold enable input; (10)Power-good flag; (11)Voltage tracking; (12)Integrated soft start; (13)Internal compensation; (14)Startup with precharged output; (15)UVLO, OVP, OCP, and thermal shutdown; (16)10-lead, 3 mm * 3 mm LFCSP_WD package.

The absolute maximum ratings of the ADP2119 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 ADP2119, please download the datasheet in www.seekic.com or www.chinaicmart.com .
