A step-down switching regulator
28 February 2001
Power Electronics / Power Management
Analog Devices' ADP3050, a current mode-controlled, 1 A, step-down switching regulator IC for industrial, instrumentation and automotive applications, chargers and as a preregulator for linear regulators, has an innovative design that allows up to 30% wider input and 20% better thermal performance than industry standard devices, simplifying system design and lowering overall system size and cost.
The ADP3050's 60 V load dump rating makes it a superior choice for automotive, industrial and instrumentation applications. The part has an integrated, 1 A, saturated NPN switch, reducing system size and cost. Spanning 3,6 V to 30 V, design engineers can use one part for a wide range of power regulation needs. The part's SO-8 package incorporates ADI's Chip-on-Lead thermal enhancement technology, improving power handling by up to 20% without bulky power packages. The ADP3050 employs advanced current mode circuit topology, so designers can use any type of output capacitor regardless of ESR (equivalent series resistance) value. Its fixed switching frequency (200 kHz) eases noise filtering and allows use of small external surface-mount components.
It has a 3% output accuracy and adjustable and fixed output options.
