Step-Down (Buck) Regulators
Analog Devices manufactures a broad line of high performance, step-down buck switching regulator ICs and buck switching controller ICs with both synchronous and nonsynchronous switches. These switching voltage regulators offer typical input voltage capability from less than 2 V up to 100 V+, switching frequencies up to 4 MHz, and high efficiency operation up to 96%. With burst mode operation, quiescent currents in the tens of micro-amps level can be attained. This combination of features allows for very small, low profile buck switching regulator circuit implementations with minimum external components.
