Tyco Intros SIPs of SuperLynx/AustinLynx/MicroLynx
Tyco Electronics Power Systems Inc. (Dallas, TX) announced new single-in-line package (SIP) versions of its 16 A SuperLynx™ II, 10 A Austin Lynx™ II and 6 A MicroLynx™ II dc-dc converters in 2.4 Vdc to 5.5 Vdc and 8.4 Vdc to 14 Vdc input-voltage ranges. The modules feature programmable output voltages that enable designers to use a standard dc-dc converter to implement various types of output-voltage sequencing when powering multiple voltages on a board.
Based on thAustin Lynx Platform, the non-isolated, point-of-load converters offer EZ-SEQUENCE power sequencing and wider input ranges with pin-to-pin compatibility. The EZ-SEQUENCE feature supports ratio-metric, voltage tracking and traditional cascading types of power sequencing. Ratio-metric and voltage tracking power sequencing allows powering devices with multiple supply voltages requirements to be met with simple circuits, thereby reducing development time.
The 2.4 Vin to 5.5 Vin, 6 A MicroLynx II converter offers 94-percent efficiency at 3.3 V full load while the 10 A Austin Lynx II and 16 A SuperLynx II converters achieve 95 percent. The power modules can be used to convert the input voltage to a tightly regulated output voltage of 0.75 Vdc to 3.3 Vdc, programmable using an external resistor. The 12 Vin MicroLynx II converters offer 89-percent efficiency at 3.3 V full load; the 12 Vin Austin Lynx II delivers 93 percent; and the 12 Vin SuperLynx II delivers 92 percent. The modules can be used to convert an input voltage ranging between 8.4 V and 14 V to a tightly regulated output voltage of 0.75 Vdc to 5 Vdc, also programmable using an external resistor.
Prices for 1,000-piece quantities are $6.90 for the Austin MicroLynx II, $9.80 for the Austin Lynx II and $11.60 for the Austin SuperLynx II. Samples are now available to order.
