APPLICATION INFORMATION

10-V N-CHANNEL FET BIAS or (VOUT1)/2 VTT VOLTAGE REFERENCE (REF_X)

TPS51020’s REF_X provides two functions depending on the operational mode. One is a linear regulator that

supply 10-V for FET switch biasing in the dual mode, the other is VTT reference voltage in the DDR mode.

If DDR is high ( > 2.2 V) then the REF_X output is a convenient 10-V, 2-mA (maximum) output, useful for biasing

N-channel FET switches typically used to manage S0, S3 and S5 sleep states where the main supply is switched

to many outputs. When VIN is < 12 V, REF_X approximately tracks VIN2 V.

If DDR is low, then the REF_X output becomes the VDDQ/2 (VO1_VDDQ/2) reference. This output is capable

of 5-mA source current and is left on even if channel two (VTT switcher) is turned off. REF_X is turned off if ENBL1

and ENBL2 are both low (see Table 2).

POWERGOOD

The TPS51020 has advanced powergood logic that allows single powergood circuit to monitor both SMPS

output voltages (see Figure 3 ).

The PGOOD terminal is an open drain output. The PGOOD pin remains low until both power supplies have

started and have been in regulation (

±7.5%) for 2048 clock pulses.
