PFM/PWM Step-Down DC/DC Controller

TC105 The TC105 is a Step-down (Buck) switching controller that furnishes output currents of up to 1A (max) while delivering a typical efficiency of 92%. The TC105 normally operates in pulse width modulation mode (PWM), but automatically switches to pulse frequency modulation (PFM) at low output loads for greater efficiency. Oscillator frequency is 300kHz, allowing use of small (22) inductors. Supply current draw is only 102 (max), and is reduced to less than 0.5w h e n the SHDN input is brought low. Regulator operation is suspended during shutdown. The TC105 accepts a maximum input voltage of 10V. By Microchip Technology Inc.
