PN8162 Overview
The Chipown PN8162 is a fully integrated quasi-resonant AC/DC converter IC embedding a quasi-resonant current-mode controller alongside a 690V high-avalanche-capability power MOSFET in a single PDFN-8 (5×6mm) package. By integrating high-voltage startup circuitry and eliminating the need for external start-up resistors and current-sense (CS) resistors, the PN8162 significantly reduces BOM complexity and PCB area — a key advantage for cost-sensitive consumer and industrial power supply designs.
Chipown has engineered the PN8162 around a proprietary hybrid modulation architecture that transitions automatically between QR-PWM, QR-PFM, and Burst-mode operation in response to load demand. This multi-mode approach, combined with a dedicated low-power device structure, delivers standby power consumption below 50mW at 230VAC, supporting compliance with energy efficiency regulations including EU CoC Tier 2 and DoE Level VI. Integrated Soft Driver technology and spread-spectrum frequency modulation — operating between 22kHz and 28kHz at light loads — actively suppress conducted and radiated EMI, minimising filtering requirements and easing certification.
The PN8162 incorporates a comprehensive protection suite covering output overvoltage protection (OVP), cycle-by-cycle overcurrent protection (OCP), overload protection (OLP), output open/short-circuit protection, secondary rectifier short-circuit protection, over-temperature protection (OTP), soft-start, and input undervoltage lockout (UVLO). Its wide supply voltage range of 9V to 38V makes the PN8162 well-suited to a broad spectrum of output voltage configurations in charger, adapter, and open-frame power supply platforms.

Frequently Asked Questions
Is PN8162 RoHS compliant?
Yes. The Chipown PN8162 is produced in full compliance with the RoHS Directive (2011/65/EU) and its amendment (EU) 2015/863, restricting the use of hazardous substances including lead, mercury, cadmium, and hexavalent chromium. RoHS compliance documentation and material declarations are available on request from ABL Semi.
What are the pin-to-pin replacements for PN8162?
The PN8162 serves as a cost-effective, functionally equivalent alternative to a range of established quasi-resonant flyback controller ICs, including the Power Integrations TNY290, onsemi NCP1380, Sanken STR-A6069H, and Infineon ICE2QR0665G. Refer to the compatibility table above for detailed substitution guidance and specific design advantages.
What is the minimum order quantity (MOQ) for PN8162?
ABL Semi offers flexible MOQ for the PN8162, supporting both prototype quantities and mass production orders. Contact us for current stock levels and pricing.
What package options are available for PN8162?
The PN8162 is available in a PDFN-8 (5×6mm) package — a thermally enhanced power dual flat no-lead format that offers superior heat dissipation compared to standard SOP-8 packages, making it well suited to higher-power charger and adapter designs. If you require an alternative package variant, contact ABL Semi to discuss current availability.
How does the PN8162’s frequency modulation improve EMI performance?
The PN8162 employs spread-spectrum frequency modulation, dithering the switching frequency between approximately 22kHz and 28kHz under light-load and standby conditions. This spreads switching noise energy across a wider frequency band rather than concentrating it at a single fundamental frequency, reducing peak EMI levels measured at conducted and radiated emission test points. Combined with Chipown’s integrated Soft Driver technology — which controls MOSFET gate drive slew rate to limit high-frequency harmonic content — the PN8162 significantly eases EMC pre-compliance and reduces the cost of input filtering components.
