产品概述
The TL497ACN is a 500mA peak step-up step-down inverting switching Voltage Regulator incorporates all the active functions required in the construction of switching voltage regulators. It also can be used as the control element to drive external components for high-power-output applications. The TL497A was designed for ease of use in step-up step-down or voltage-inversion applications requiring high efficiency. The TL497A is a fixed-on-time variable-frequency switching-voltage-regulator control circuit. The switch-on time is programmed by a single external capacitor connected between FREQ CONTROL and GND. This capacitor CT is charged by an internal constant-current generator to a predetermined threshold. The charging current and the threshold vary proportionally with VCC.
