TC120 PWM/PFM Step-Down Combination Regulator/Controller

TC120 is a 300kHz PFM/PWM step-down (Buck) DC/ DC regulator/controller combination for use in systems operating from two or more cells, or in line-powered applications. It uses PWM as the primary modulation scheme, but automatically converts to PFM at low output loads for greater efficiency. It requ.
