TF6002 - 2A, 26V Synchronous Rectified Step-Down Converter

Product Type: DC-DC Regulator
Current Status: Release

Product Overview
The TF6002 is a monolithic synchronous buck regulator featuring integrated 130 mΩ MOSFETs that provide continuous 2A output load current. It operates over a wide 4.5V to 26V input voltage range and provides output voltage from 0.923V to 23V at up to 93% efficiency. Its current mode control circuitry provides fast transient response and cycle-by-cycle current limit.
The TF6002 operates at fixed 340 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 TF6002 is offered in 8-pin SOIC narrow package. It operates over an extended -40 °C to +85 °C temperature range.
