MAX1743

The MAX1743 converts +5 V to ±12 V or ±15 V, with no external components required.It supplies 125 mA at ±12 V or 100 mA at ±15 V.Pin strapping selects ±12 V or ±15 V operation.

Features of the MAX1743 are:(1)no external components required; (2)pin-strap selectable output voltage; (3)82% efficiency; (4)24-pin wide DIP footprint; (5)low output ripple; (6)2.0 V reference output; (7)outputs guaranteed to ±4% over all specified line, load, and temperature conditions.

The absolute maximum ratings of the MAX1743 can be summarized as:(1): V+ to GND is +7 V,-0.3 V(±12 V mode); (2): VO+ to GND is +17 V, 0V; (3): VO- to GND is 0 V , -20 V; (4): Vo- to V+ is 0 V to -23 V; (5): Vref to GND is V+ + 0.3 V,-0.3 V; (6): Vo+ source current is 1 A; (7): Vo- to GND short-circuit duration is 1 minute; (8): operating temperature range is 0 to 70; (9): lead temperature(soldering, 10 sec) is +300.
