ADP1822 meets growing need for sequencing, tracking and margining features in medical instrumentation, wireless base station and network computing applications.Analog Devices is introducing a new single-phase, high-current switching controller ideal for applications that demand regulated precision and reliability, such as wireless base stations and network computing systems. The ADP1822 is a synchronous, fixed-frequency switching controller well suited for high current applications - such as communications infrastructure systems and high performance servers.
High Power and Precision
The ADP1822 drives an all N-channel power stage to regulate an output voltage as low as 0.6 V with 20 A load current. The controller features a +/1 percent 0.6 V on-board voltage reference, making it ideal for next generation DSPs, FPGAs, core supplies and microprocessors, which require a low and accurate power supply voltage under 1 V. The ADP1822 works particularly well with Analog Devices' embedded processors.
The device operates from a 3.0 V to 5.5 V supply, and its wide voltage range of 1.0 V to 24 V provides flexibility for designers developing higher voltage applications. Additional features include programmable soft-start, power good indicator, shutdown, thermal overload protection, over-voltage protection and under voltage lockout.
Availability and Pricing
The ADP1822 is available now in a 24-lead QSOP (small outline package) at $1.80 per unit in 1,000-unit quantities. and is offered over the extended industrial temperature range of -40 degrees C to +85 degrees.
