TS19601
700mA High Voltage Adjustable Current Regulator
With Enable Control
Application Information
TS19601 is a high voltage, low dropout current regulator for maximum output current up to 700mA with OE pin
control. The current could be linearly adjusted through variable resister connected to ISET pin, or by PWM control
via OE pin. Although the absolute maximum rating of OUT pin 75V, the dropout voltage between OUT pin and
GND pin should not be too large when current is sinking because of the thermal dissipation capability of the
package.
Here are some of the typical application examples:
DC Voltage Input
Any DC voltage level between 5V to 50V could be adopted as power source VDD for typical application of
TS19601 as long as VDD is larger than the total forward voltage drop of the LED string (at expecting current) by
0.35V. If 50V ~ 60V voltage level is adopted as power source to positive end of the LED string, one Zener shunt
regulator could be used to provide appropriate voltage to VDD pin.
