MC33063ADR2G

The MC33063ADR2G is one member of the MC33063A family of 1.5 A, step.up/down/inverting switching regulators. This kind of monolithic control circuit containing the primary functions required for DC to DC converters. MC33063ADR2G consists of comparator, an internal temperature compensated reference, controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch and is specifically designed to be incorporated in step-down and step-up and voltage-inverting applications with a minimum number of external components.

Features of the MC33063ADR2G are:(1)operation from 3.0 V to 40 V input; (2)low standby current; (3)current limiting; (4)output switch current to 1.5 A; (5)output voltage adjustable; (6)frequency operation to 100 kHz; (7)precision 2% reference; (8)Pb-free packages are available.

The absolute maximum ratings of the MC33063ADR2G can be summarized as:(1)comparator input voltage range:-0.3 to +40 Vdc;(2)power supply voltage:40 Vdc;(3)switch collector voltage:40 Vdc;(4)switch emitter voltage (VPin 1=40 V):40 Vdc;(5)switch collector to emitter voltage:40 Vdc;(6)driver collector voltage:40 Vdc;(7)driver collector current:100 mA;(8)switch current:1.5 A;(9)storage temperature range:-65 to +150 °C;(10)operating ambient temperature range:-40°C to +85°C;(11)operating junction temperature:+150 °C.
