DESCRIPTION/ORDERING INFORMATION
The MC33063A and MC34063A are easy-to-use ICs containing all the primary circuitry needed for building
simple dc-dc converters. These devices primarily consist of an internal temperature-compensated reference, a
comparator, an oscillator, a PWM controller with active current limiting, a driver, and a high-current output switch.
Thus, the devices require minimal external components to build converters in the boost, buck, and inverting
topologies.
The MC33063A is characterized for operation from –40°C to 85°C, while the MC34063A is characterized for
operation from 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating
conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
The package thermal impedance is calculated in accordance with JESD 51-7.

Low duty-cycle pulse testing is used to maintain junction temperature as close to ambient temperature as possible.
In the non-Darlington configuration, if the output switch is driven into hard saturation at low switch currents (≤300 mA) and high driver
currents (≥30 mA), it may take up to 2 μs for the switch to come out of saturation. This condition effectively shortens the off time at
frequencies ≥30 kHz, becoming magnified as temperature increases. The following output drive condition is recommended in the
non-Darlington configuration:
Forced β of output switch = IC,SW / (IC,driver – 7 mA) ≥ 10, where ~7 mA is required by the 100-Ω resistor in the emitter of the driver to
forward bias the Vbe of the switch.

If the output switch is driven into hard saturation (non-Darlington configuration) at low switch currents (≤300 mA) and
high driver currents (≥30 mA), it may take up to 2 μs to come out of saturation. This condition will shorten the off time
at frequencies ≥30 kHz and is magnified at high temperatures. This condition does not occur with a Darlington
configuration because the output switch cannot saturate. If a non-Darlington configuration is used, the output drive
configuration in Figure 7b is recommended.

Vsat = Saturation voltage of the output switch
VF = Forward voltage drop of the chosen output rectifier
The following power-supply parameters are set by the user:
Vin = Nominal input voltage
Vout = Desired output voltage
Iout = Desired output current
fmin = Minimum desired output switching frequency at the selected values of Vin and Iout
Vripple = Desired peak-to-peak output ripple voltage. The ripple voltage directly affects the line and load
regulation and, thus, must be considered. In practice, the actual capacitor value should be larger than the
calculated value, to account for the capacitor's equivalent series resistance and board layout.

TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder
temperature.
