TJ34063A

HTC Korea TJ34063A series is a monolithic control circuit delivering the main  functions for DC-DC voltage converting. The device contains an internal temperature compensated reference, comparator, duty cycle controlled oscillator with an active  current limit circuit driver and high current output switch. Output voltage is adjustable through two external resistors with a 2% reference accuracy. Employing a minimum number of external components the TJ34063A devices series is designed for Step-Down, Step-Up and  Voltage-Inverting applications.
