Product Overview
The MAX845EUA+ is an isolated transformer driver for PCMCIA applications in 8 pin µMAX package. It drives a low-profile centre tapped transformer primary from a 5V or 3.3V DC power supply. The secondary can be wound to provide any isolated positive or negative voltage at powers up to 750mW. The MAX845 consists of an oscillator followed by a toggle flip-flop. The flip-flop generates two 50% duty cycle square waves which are complementary at half the oscillator frequency (450KHz, min). These two signals drive the ground-referenced N-channel power switches. Internal circuitry ensures break-before-make action between the two switches. A low power shutdown disables both the switches and the oscillator, reducing power consumption. Typical applications include PCMCIA modem cards, isolated data acquisition, isolated interface power supply, noise-immunity communications interface, bridging ground differences, process control and low power LAN networks.
- Supply voltage range is 2.5V to 6V
- Operating temperature range from -40°C to 85°C
- Minimum switching frequency is 450KHz
- Ultra low input supply current ripple
- Low power shutdown reduces the supply current to 5μW
- Low output ripple permits miniature output capacitors
