TMI3408F 1.5MHz, 1.2A Synchronous Step-Down Converter with Force PWM Mode
●The TMI3408F is a constant frequency 1.5MHz, peak current mode step-down converter with force PWM operation mode. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. The output voltage can be regulated as low as 0.6V. The TMI3408F can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. This device adopts peak current mode control and force PWM mode and has fast load transient response.
