Product Summary

The MAX743CWE DC-DC converter IC contains all the active circuitry needed to built small, dual-output power supplies. Relying on simple two-terminal inductors rather than transformers, the MAX743CWE regulates both outputs independently to within ±4% over all conditions of line voltage, temperature, and load current. The applications of the MAX743CWE include DC-DC converter module replacement, distributed power systems, computer peripherals, portable instruments

Parametrics

MAX743CWE absolute maximum ratings: (1)supply voltage (V+ or AV+ to GND): +7 V, -0.3 V (±12 V mode); (2)output switch voltages (LX+ to GND): +17 V, -0.3 V, (LX- to V+): -23 V, +0.3 V; (3)output switch currents (LX+ sink current, peak): 2.0 A, (LX- source current, peak): -2.0 A; (4)operating temperature range: 0 to +70 ℃; (5)junction temperature: +150 ℃; (6)storage temperature range: -65 to +160 ℃.

Features

MAX743CWE features: (1)generates ±100 mA or ±125 mA; (2)specs guaranteed for in-circuit performance; (3)±4% output tolerance max over temp, line, and load; (4)82% typ efficiency; (5)low-noise, current-mode feedback; (6)on-board current limiting; (7)thermal shutdown protection; (8)undervoltage lock-out and soft-start; (9)switches from ±15 V to ±12 V under logic control.
