ADP2121

The ADP2121 is designed as one kind of 600 mA, 6 MHz, synchronous step-down DC-to-DC converter device that can be used in wide range of applications such as (1)mobile phones; (2)digital cameras; (3)digital audio; (4)portable equipment. Also this device can source up to 600 mA and is internally compensated to minimize external components.

Features of the ADP2121 are:(1)Peak efficiency: 92%; (2)Operating frequency: 6 MHz; (3)Typical quiescent current in auto mode: 36 A; (4)Fixed output voltage: 1.8 V, 1.82 V, 1.85 V, 1.875 V, 2.3 V; (5)Maximum guaranteed load current: 600 mA at VIN = 2.7 V to 5.5 V; (6)Input voltage: 2.3 V to 5.5 V; (7)Typical shutdown supply current: 0.3 A; (8)Automatic power-saving mode; (9)Compatible with tiny multilayer inductors; (10)Internal synchronous rectifier; (11)Internal compensation; (12)Internal soft start; (13)Output to ground short-circuit protection; (14)Cycle-by-cycle current-limit protection; (15)Enable/shutdown logic input; (16)Undervoltage lockout; (17)Thermal shutdown protection.

The absolute maximum ratings of the ADP2121 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, SW to GND: -0.3 V to VIN + 0.2 V;(6)EN, MODE to GND: -0.3 V to VIN.etc. If you want to know more information about the ADP2121, please download the datasheet in www.seekic.com or www.chinaicmart.com .
