32 / 165 page i.MX 6Dual/6Quad Automotive and Infotainment Applications Processors, Rev. 2.3 32 Freescale Semiconductor Electrical Characteristics • Analog regulation mode. The regulation FET is controlled such that the output voltage of the regulator equals the programmed target voltage. The target voltage is fully programmable in 25 mV steps. For additional information, see the i.MX 6Dual/6Quad reference manual (IMX6DQRM). 4.3.2 Regulators for Analog Modules 4.3.2.1 LDO_1P1 The LDO_1P1 regulator implements a programmable linear-regulator function from VDD_HIGH_IN (see Table 6 for minimum and maximum input requirements). Typical Programming Operating Range is 1.0 V to 1.2 V with the nominal default setting as 1.1 V. The LDO_1P1 supplies the USB Phy, LVDS Phy, HDMI Phy, MIPI Phy, and PLLs. A programmable brown-out detector is included in the regulator that can be used by the system to determine when the load capability of the regulator is being exceeded to take the necessary steps. Current-limiting can be enabled to allow for in-rush current requirements during start-up, if needed. Active-pull-down can also be enabled for systems requiring this feature. For information on external capacitor requirements for this regulator, see the Hardware Development Guide for i.MX 6Quad, 6Dual, 6DualLite, 6Solo Families of Applications Processors (IMX6DQ6SDLHDG). For additional information, see the i.MX 6Dual/6Quad reference manual (IMX6DQRM). 4.3.2.2 LDO_2P5 The LDO_2P5 module implements a programmable linear-regulator function from VDD_HIGH_IN (see Table 6 for min and max input requirements). Typical Programming Operating Range is 2.25 V to 2.75 V with the nominal default setting as 2.5 V. The LDO_2P5 supplies the SATA Phy, USB Phy, LVDS Phy, HDMI Phy, MIPI Phy, E-fuse module and PLLs. A programmable brown-out detector is included in the regulator that can be used by the system to determine when the load capability of the regulator is being exceeded, to take the necessary steps. Current-limiting can be enabled to allow for in-rush current requirements during start-up, if needed. Active-pull-down can also be enabled for systems requiring this feature. An alternate self-biased low-precision weak-regulator is included that can be enabled for applications needing to keep the output voltage alive during low-power modes where the main regulator driver and its associated global bandgap reference module are disabled. The output of the weak-regulator is not programmable and is a function of the input supply as well as the load current. Typically, with a 3 V input supply the weak-regulator output is 2.525 V and its output impedance is approximately 40 . For information on external capacitor requirements for this regulator, see the Hardware Development Guide for i.MX 6Quad, 6Dual, 6DualLite, 6Solo Families of Applications Processors (IMX6DQ6SDLHDG). For additional information, see the i.MX 6Dual/6Quad reference manual (IMX6DQRM). |
