HP1510 is an AC-DC switching power supply converter controller chip with a very wide VCC voltage range, suitable for 65W PD fast charging applications.HP1510 has very low start-up and operating currents, providing green mode (Green Mode), pulse mode (Burst Mode) function and valley-opening function, reducing standby power consumption.HP1510 is equipped with jitter function, slope compensation, leading edge blanking function, line voltage compensation function and multi-step output voltage adaptive loop gain adjustment function.
HP1510 uses a constant current source to drive the output, which can improve the EMI performance of the switching power supply system.HP1510 provides a variety of automatic recovery protection modes, including: cycle-by-cycle current limit (OCP), over temperature protection (OTP), input voltage undervoltage and overvoltage protection, VCC overvoltage protection, secondary side Schottky short-circuit protection, low voltage shutdown (UVLO), overpower protection (OPP).HP1510 is available in a SOT23-6L package.
