TC120 Description
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-pow.
TC120 Features
* Internal Switching Transistor Supports 600mA Output Current
* External Switching Transistor Control for Output Currents of 2A+
* 300kHz Oscillator Frequency Supports Small Inductor Size
* Short Circuit Protection
* Built-In Undervoltage Lockout
* 95%
TC120 Applications
* It uses PWM as the primary modulation scheme, but automatically converts to PFM at low output loads for greater efficiency. It requires only an external inductor, Schottky diode, and two capacitors to implement a step-down converter having a maximum output current of 600mA (VIN = 5V, VOUT = 3.3V).
