TF6006 - 500mA, 26V Synchronous Rectified Step-Down Converter

Product Type: DC-DC Regulator
Current Status: Advance Info

Product Overview
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.
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 an 8-pin DFN 2mm x 3mm package
and operates over an extended -40 °C to +85 °C temperature range.
