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.
