TF6006  
500 mA, 26V Synchronous Rectified  
Step-Down Converter  
Features  
Description  
The TF6006 is a monolithic synchronous buck regulator  
featuring integrated MOSFETs that provide continuous 500 mA  
output load current. It operates over a wide 4.5V to 26V input  
voltage range and provides output voltage from 0.8V to 23V at  
up to 93% efficiency. Its current mode control circuitry provides  
fast transient response and cycle-by-cycle current limit.  
500 mA continuous output current  
Wide input voltage range: 4.5V to 26V  
Wide output voltage range: 0.8V to 23V  
High, >90%, efficiency (VIN = 12V, 40mA < IOUT < 0.3A)  
enabled by integrated MOSFET switches  
Operates at fixed 500 kHz frequency for small filter size  
3 µA (MAX) shut-down supply current  
Programmable soft-start, cycle-by-cycle over-current  
protection and input under-voltage lockout  
Industrial temperature range: -40 °C to +85 °C  
The TF6006 operates at fixed 500 kHz switching frequency. It  
features programmable soft-start which prevents inrush current  
at turn-on. In shut-down mode it draws only 3 µA (MAX).  
The TF6006 is offered in 8-pin DFN 2mm x 3mm package and  
operates over an extended -40 °C to +85 °C temperature range.
