Elevation Semiconductor released two high -efficiency power integration circuits, which covers a smaller area and used for fast charging solutions. HL9510 and HL9512 are anti -gratifying PWM controller ICs. They work in QR mode, which greatly improves system efficiency and power density. These integrated circuits provide a constant output voltage adjustment through optocoupler feedback controller or diversion regulator, and integrated high -voltage startup.
HL9510 is used to integrate internal high -voltage startup circuits, while HL9512 can be completed by integrated AUX and ST pins of integrated IC. Their protection includes VDD -OVP, lighting protection, Dmago -OVP, DMAGO -UVP, IC internal OTP and IC external hot SD.
HL9510 provides a 10 -pin SOIC package, which is very suitable for USB PD/QC portable equipment battery charger, high -efficiency AC/DC power adapter, and power supply to fix or variable output voltage. HL9512 uses the same packaging, suitable for smartphones, tablet computer battery chargers, portable equipment adapters, and anti -gratifying power suppliers with low/or variable output voltage.
The BROWN-in voltage is programmed by a external DMAG foot resistance and provides a wide range of VDD working range to cover the application of variable output mode, including USB-PD/PPS or traditional DP/DN protocol communication. Its protection also realizes the automatic restart mode. VDD -OVP, DMAGO -OVP and external SD protection can be equipped with automatic restart or locking mode, Dmago -UVP can configure automatic restart or automatic restart mode for a long time.
"The new anti -gratifying PWM controller enhances system efficiency and power density, adding another dimension to our fast charging solution combination. Their small occupation area is also played in the key application of limited board space. Key role, said David Nam, chief executive officer of Elevation Semiconductor.
