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.
