Power Integrations, Inc. (NASDAQ: POWI), headquartered in San Jose, California (Silicon-Valley), is a high-voltage analog-IC semiconductor specializing AC-DC power-conversion + emerging-EV-Onboard-Charger + emerging-Power-Factor-Correction (PFC) + emerging-data-center + emerging-fast-charge providing distinctive multi-cycle InnoSwitch + LinkSwitch + TinySwitch + LYTSwitch + HiperPFS + Hiper integrated-circuit-families services to US + Asia-Pacific + EU + emerging-multi-jurisdiction-semiconductor + emerging-EV-OEM customer base. Founded 1988 by Balu Balakrishnan (Indian-American semiconductor + Stanford-and-Silicon-Valley-semiconductor entrepreneur, ~37+ year founding-CEO); 1997 NASDAQ IPO. Multi-decade strategic-evolution: 1988-1997 Power-Integrations-and-Balu-Balakrishnan + Silicon-Valley-Stanford-semiconductor + AC-DC-power-conversion platform; 1997 NASDAQ IPO; 1997-2024 Power-Integrations + InnoSwitch + LinkSwitch + TinySwitch + LYTSwitch + HiperPFS + Hiper + Apple-iPhone + emerging-EV-Onboard-Charger + emerging-USB-PD; 2020-2025 post-COVID + emerging-EV-and-fast-charge + emerging-EV-Onboard-Charger + emerging-data-center + emerging-PFC. Under founder-CEO Balu Balakrishnan (since 1988, ~37+ year founder-and-CEO), FY2025 closes with selected various aggregate revenue ~$0.45-0.55B, adj. EBITDA ~$110-160M, adj. EPS ~$1.55-2.25, substantial cash ~$280-350M, and ~55-57M shares outstanding. The first deep-dive — High-voltage analog-IC + AC-DC power-conversion + emerging-EV-Onboard-Charger franchise — covers entire high-voltage analog-IC semiconductor + AC-DC power-conversion + emerging-EV-Onboard-Charger + emerging-PFC business + Power-Integrations-and-InnoSwitch-and-LinkSwitch-and-HiperPFS positioning. Product portfolio: InnoSwitch (USB-PD + USB-Type-C + Apple-iPhone-USB-C + fast-charger), LinkSwitch, TinySwitch, LYTSwitch, HiperPFS, Hiper + emerging-EV-Onboard-Charger + emerging-PFC.
