LN9T26 DIP-7

توضیحات

The LN9T26 is a high performance, highly integrated current mode PWM controller that makes it easy to build low standby

power, low cost, high performance solutions to meet CoC V5 and DoE VI energy efficiency in applications. The PWM switchingfrequency is internally set by the chip and has full temperature compensation. The maximum value is set at 65 kHz. Under

no-load or light load conditions, the IC can operate in intelligent interrupt mode to reduce switching losses, so it can be
achieved good conversion efficiency while having lower standby power consumption. The low VDD startup current and
operating current allow the LN9T26 to have very high reliability and longevity. A resistor with larger resistance can be used
to complete the circuit startup, which also reduces the loss of the startup resistor, further reduces the system standby power.
The built-in current ramp compensation greatly optimizes the reliability of the circuit over large PWM duty cycles and avoids
subharmonic oscillations that may occur. The built-in leading edge blanking circuit avoids the inductance turn-on current
spike interference with current sampling and the effect on the snubber diode reverse recovery current, and the external no
