ADP1872

The ADP1872 is designed as one kind of versatile current-mode, synchronous step-down controller device that can be used in (1)Telecom and networking systems; (2)Mid to high end servers; (3)Set-top boxes; (4)DSP core power supplies applications. And this device operates over the -40°C to +125°C junction temperature range and is available in a 10-lead MSOP.

Features of the ADP1872 are:(1)Power input voltage as low as 2.75 V to 20 V; (2)Bias supply voltage range: 2.75 V to 5.5 V; (3)Minimum output voltage: 0.6 V; (4)0.6 V reference voltage with ±1.0% accuracy; (5)Supports all N-channel MOSFET power stages; (6)Available in 300 kHz, 600 KHz, and 1.0 MHz options; (7)No current-sense resistor required; (8)Power saving mode (PSM) for light loads (ADP1873 only); (9)Resistor-programmable current-sense gain; (10)Thermal overload protection; (11)Short-circuit protection; (12)Precision enable input; (13)Integrated bootstrap diode for high-side drive; (14)140 A shutdown supply current; (15)Starts into a precharged load; (16)Small, 10-lead MSOP package.

The absolute maximum ratings of the ADP1872 can be summarized as:(1)VREG to PGND, GND: -0.3 V to +6 V;(2)VIN to PGND: -0.3 V to +28 V;(3)FB, COMP/EN to GND: -0.3 V to (VREG + 0.3 V);(4)DRVL to PGND: -0.3 V to (VREG + 0.3 V);(5)SW to PGND: -2.0 V to +28 V;(6)Storage Temperature Range: -65°C to +150°C;(7)Operating Temperature Range: -40°C to +125°C;(8)Lead Temperature (10 sec): 300°C;(9)Maximum Soldering Lead Temperature (10 sec): 300°C.
