Providing a pair of high-efficiency pwm step-down dc-dc converters in a 2.5mm x 2.00mm package, the PAM2322AGEAR from Diodes Incorporated is tailored to the needs of wireless and DSL modem applications. Its pulse-skipping mode enables a reduction in quiescent current under light load operation, helping to maximize portable device battery life. Further power savings are achieved by the converters’ 100% duty cycle, allowing systems to operate even at the lowest voltage supply. With an input voltage range from 2.7V to 5.5V, the 17-pad W-FLGA2050 packaged converters will support the use of single Li+ / Li polymer cells, multiple alkaline/NiMH cells, USB power supplies and many other standard power sources.

The device offers a 1A, 1.8V fixed voltage output and a 2A, adjustable (0.9V to VIN) voltage output, each with an independent active-high channel enable pin. Integration of an internal power switch and synchronous rectifier on each output, combined with a high operating frequency of 1.2MHz means PAM2322AGEAR also minimizes the size and quantity of external components that are required.
