Operating from either a 3.3 Vdc, 5 Vdc or 12 Vdc input, the modules generate a VTT output that will source or sink up to 6 A of current to accurately track their VREF input. VTT is the required bus termination supply voltage, and VREF is the reference voltage for the memory and chipset bus receiver comparators. VREF is usually set to half the VDDQ power supply voltage. The PTHxx050Y series employs an actively switched synchronous rectifier output to provide state of the art stepdown switching conversion. The products are small in size and are an ideal choice where space, performance and high efficiency are desired. All specifications are typical at nominal input, VREF = 1.25 V, full load at 25 °C unless otherwise stated. Cin, Co1 and Co2 = typical value OUTPUT SPECIFICATIONS Output current (over ∆VREF range) Tracking range for VREF Tracking tolerance to VREF (VTT - VREF) (over line, load and temperature) Ripple and noise Load transient response (See Note 5) Output capacitance: Non-ceramic values (See Notes 5 and 6) Ceramic values (See Note 5) (See Note 7) 20 MHz bandwidth All models Continuous (See Note 1) Repetitive pulse (See Note 2) ±6 A ±8 A 0.55-1.8 V -10 mV to +10mV INPUT SPECIFICATIONS CONTD.
