TF6003概述：3A,26V，340KHz同步整流降压DC-DC转换器
The TF6003 is a monolithic synchronous buck regulator featuring integrated 100mΩ MOSFETs that provide continuous 3A 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 TF6003 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 TF6003 is offered in a thermally enhanced 8-pin SOIC package. It operates over an extended -40 °C to +85 °C temperature range. Features
