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.
NOTES: 1. Maximum power dissipation is a function of T (max), θ , and T . The maximum allowable power dissipation at any allowable

NOTES: 3. Low duty-cycle pulse testing is used to maintain junction temperature as close to ambient temperature as possible.
4. 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:

NOTE A: 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 2b is recommended.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2)
Eco Plan - May not be currently available - please check http://www.ti.com/productcontent for the latest availability information and additional
product content details.
None: Not yet available Lead (Pb-Free).
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.
Green (RoHS & no Sb/Br): TI defines "Green" to mean "Pb-Free" and in addition, uses package materials that do not contain halogens,
including bromine (Br) or antimony (Sb) above 0.1% of total product weight.
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDECindustry standard classifications, and peak solder
temperature.
