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

ambient temperature is P = (T (max) − T )/θ . Operating at the absolute maximum T of 150°C can affect reliability.

2. The package thermal impedance is calculated in accordance with JESD 51-7.

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.

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.
