FEATURES  
DESCRIPTION  
The TPS54062 device is a 60V, 50-mA, synchronous  
step-down converter with integrated high side and low  
side MOSFETs. Current mode control provides  
simple external compensation and flexible component  
selection. The non switching supply current is 89µA.  
Using the enable pin, shutdown supply current is  
reduced to 1.7µA.

89 µA (typical) Operating Quiescent Current  
100kHz to 400kHz Switching Frequency  
Synchronizes to External Clock  
Internal Slow Start  
Under voltage lockout is internally set at 4.5V, but  
can be increased using the accurate enable pin  
threshold. The output voltage startup ramp is  
controlled by the internal slow start time.  
0.8V ±2% Voltage Reference  
Stable with Ceramic Output Capacitors or Low  
Cost Aluminum Electrolytic  
Cycle-by-Cycle Current Limit, Thermal and  
Frequency Fold Back Protection  
Adjustable switching frequency range allows  
efficiency and external component size to be  
optimized. Frequency fold back and thermal  
shutdown protects the part during an overload  
condition.
