High Current Output Drivers  
Application Information  
The FAN5037 high current output driver (DRV) contains  
high speed bipolar power transistors configured in a  
push-pull configuration. The output driver is capable of sup-  
plying 0.5A of current in less than 100ns. The driver’s power  
and ground are separated from the overall chip power and  
ground for added switching noise immunity.  
The FAN5037 contains a precision trimmed zero TC voltage  
reference, a constant-on-time architecture controller, a high  
current output driver, and a low offset error amp. The  
detailed block diagram in Figure 1 shows how the FAN5037  
works together with external components to achieve a high-  
performance switching power supply.  
Internal Reference  
Switch-Mode Control Loop  
The reference in the FAN5037 is a precision band-gap type  
reference. Its temperature coefficient is trimmed to provide a  
near zero TC.  
The main control loop for the switch-mode converter consists  
of a current conditioning amplifier and a voltage conditioning  
amplifier. The voltage amplifier compares the voltage from the  
internal reference with the converter’s output voltage divided  
by an external resistor divider. The current amplifier senses the  
current by comparing the voltages at the IFBH and IFBL pins,  
which are attached to either side of the current sense resistor.  
The signals from the voltage and current amplifiers are  
summed together, the result being used to control the off-time  
of the oscillator. The current feedback signal is also used as  
part of the FAN5037 short-circuit protection.  
Constant-On-Time Oscillator  
The FAN5037 switch-mode oscillator is designed as a fixed  
on-time, variable off-time oscillator. The constant-on-time  
oscillator consists of a comparator, an external capacitor, a  
fixed current source, a variable current source, and an analog  
switch that selects between two threshold voltages for the  
comparator. The external timing capacitor is alternately
