General Description The MAX8563/MAX8564/MAX8564A ultra-low-output dual and triple LDO controllers allow flexible and inexpensive point-of-load voltage conversion in motherboards, desknotes, notebooks, and other applications. These parts feature a 0.5V reference voltage with ±1% accuracy providing tight regulation of the output volt- age. The MAX8563 has three n-channel MOSFET con- troller outputs, and the MAX8564/MAX8564A has two controller outputs. Each controller output is adjustable from 0.5V to 3.3V when VDD = 12V and between 0.5V and 1.8V when VDD = 5V. Each output is independently enabled and asserts a POK signal when the output reaches 94% of the set value. Each output is protected against a soft short-circuit condition by an undervoltage comparator that disables the output when it drops to under 80% of the set voltage for more than 50µs. For a catastrophic short condition, the regulators are shut down immediately if the output drops below 60% of the set voltage. The MAX8563 is available in a 16-pin QSOP package, and the MAX8564/MAX8564A are available in a 10-pin µMAX® package.

Detailed Description The MAX8563/MAX8564/MAX8564A triple and dual LDO controllers allow flexible and inexpensive voltage conversion by controlling the gate of an external n-MOSFET in a source-follower configuration. The MAX8563/MAX8564/MAX8564A consist of multiple identical LDO controllers. Each LDO controller features an enable input (EN_) and a power-OK output (POK_). The MAX8563/MAX8564/MAX8564A also include a 0.5V reference, an internal regulator, and an undervoltage lockout (UVLO). The transconductance amplifier mea- sures the feedback voltage on FB_ and compares it to an internal 0.5V reference connected to the positive input. If the voltage on FB_ is lower than 0.5V, the cur- rent output on the gate-drive output DRV_ is increased. If the voltage on FB_ is higher than 0.5V, the current out- put on the gate-drive output is decreased. Bias Voltage (VDD), UVLO, and Soft-Start The MAX8563/MAX8564/MAX8564A bias current for internal circuitry is supplied by VDD. The VDD voltage range is from 4.5V to 13.2V. If VDD drops below 3.76V (typ), the MAX8563/MAX8564/MAX8564A assume that the supply and reference voltages are too low and acti- vate the UVLO circuitry. During UVLO, the internal regu- lator (VL) and the internal bandgap reference are forced off, DRV_ is pulled to GND, and POK_ is pulled low. Before any internal startup circuitry is activated, VDD must be above the UVLO threshold. After UVLO indicates that VDD is high enough, the internal VL regulator, the internal bandgap reference, and the bias currents are activated. If EN_ is logic-high after the internal reference and bias currents are activated, then the corresponding DRV_ out- put initiates operation in soft-start mode. Once the voltage on FB_ reaches 94% of the regulation threshold, the full output current of the LDO controller is permitted. When an LDO is activated, the respective DRV_ is pulled up from GND with a typical soft-start current of DRV soft- start. The soft-start current limits the slew of the output voltage and limits the initial spike of current that the drain of the external n-MOSFET receives. The size of the com- pensation capacitor (CC) limits the slew rate (see Figure 3). This output voltage slew rate is equal to (DRV_soft- start /CC)mV/ms, where CC is in µF. The maximum startup drain current is the ratio of COUT to CC multiplied by the soft-start current. Input Voltage (Drain Voltage of the External n-MOSFET) The minimum input voltage to the drain of the n-MOSFET is a function of the desired output voltage and the dropout voltage of the n-MOSFET. Details on calculating this value are covered in the Power MOSFET Selection section. The maximum input voltage to the drain of the n-MOSFET is a function of the breakdown voltage and the thermal conditions during operation. The breakdown voltage from drain to source is normally provided in the MOSFET data sheet. The theoretical maximum input voltage is the set output voltage plus the breakdown voltage. The thermal constraint is usually the largest concern when discussing maximum input voltage. Details on calculating this value are covered in the Power MOSFET Selection section. The MOSFET package and thermal relief on the board are the largest contributors to removing heat from the n-MOSFET. Since output voltage is normally set and maximum output current is fixed, the input voltage becomes the only variable that determines the maxi- mum power dissipated. Thus, the maximum input volt- age is limited by the power capability of the n-MOSFET, if it is less than the breakdown voltage, which is most often the case. Ensure input capacitors handle the maximum input voltage. During a power-up sequence where VDD and EN_ rise before the input to the drain of the n-MOSFET, the MAX8563/MAX8564/MAX8564A drive DRV_ high but the output does not rise. As DRV_ rails and VFB_ is still below 80% of the regulation voltage, the MAX8563/MAX8564/ MAX8564A assume that an output short-circuit fault is present and shut down that regulator. To avoid this error condition, connect a resistor-divider from VDD to IN_ with the middle node connected to the respective EN_ (see Figure 4). Use the following equations to calculate the resistor values.
