产品概述

The MAX845ESA+ is an Isolated Transformer Driver for PCMCIA applications. The MAX845 provides an isolated power supply small enough to fit in thin PCMCIA cards and space-sensitive applications. It drives a low-profile centre-tapped transformer primary from a 5 or 3.3VDC 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, minimum). 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.
  • 450kHz Minimum switching frequency
  • Ultralow input supply current ripple
  • 5µW Low-power shutdown mode
  • Low output ripple permits miniature output capacitors
  • Bridge Ground Differentials; Isolated Data Acquisition; Isolated Interface Power Supply;
  • Low-Power LAN Networks; Medical Equipment; Noise-Immunity Communications Interface; PCMCIA Modem Cards; Process Control
