TC110 Datasheet (Microchip) - PFM/PWM Step-Up DC/DC Controller

TC110, PFM/PWM Step-Up DC/DC Controller

The TC110 is a step-up (Boost) switching controller that furnishes output currents of up to 300mA while delivering a typical efficiency of 84%.

The TC110 normally operates in pulse width modulation mode (PWM), but automatically switches to pulse frequency modulation (PFM) at low output loads for gre
