The MAX845 provides an isolated power supply small  
enough to fit in thin PCMCIA cards and space-sensitive  
applications. It drives a low-profile center-tapped trans-  
former primary from a 5V or 3.3V DC power supply. The  
secondary can be wound to provide any isolated posi-  
tive or negative voltage at powers up to 750mW.  
Transformer Driver for Ultra-Thin 5V-µs Transformers  
Isolated DC-to-DC Power Supply for PCMCIA  
Applications  
450kHz Minimum Switching Frequency  
Ultra-Low Input Supply Current Ripple  
Single +5V or +3.3V Supply  
The MAX845 consists of an oscillator followed by a tog-  
gle 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 switch-  
es. Internal circuitry ensures break-before-make action  
between the two switches.  
5µW Low-Power Shutdown Mode  
8-Pin SO and µMAX Packages  
Low Output Ripple Permits Miniature Output  
Capacitors  
A low-power shutdown disables both the switches and  
the oscillator, reducing power consumption. An evalua-  
tion kit (MAX845EVKIT-MM) is available to evaluate low-  
profile 5V 40mA and 5V 100mA applications.
