STMicroelectronics Unveils Lower-Cost PMICs With Reduced Power Rails

Why It Matters

By offering a cheaper, smaller PMIC option, STMicroelectronics enables OEMs to lower bill‑of‑materials and board‑space costs while still meeting the power needs of emerging edge‑computing applications. This move could shift a sizable portion of the market away from discrete power solutions toward integrated, cost‑optimized chips.

Key Takeaways

• STPMIC1L and STPMIC2L cut price by up to 50%
• Power rail count reduced to simplify designs and shrink footprints
• 60% of STM32MP1 users previously chose full‑feature PMICs
• New chips support 2.8‑5.5 V input, -40 °C to 125 °C
• Target markets include POS terminals, scanners, gateways, edge devices

Pulse Analysis

The power‑management IC market has long been dominated by feature‑rich solutions that prioritize flexibility over cost. As edge computing proliferates, manufacturers increasingly demand compact, affordable power blocks that can be integrated into tight form factors. STMicroelectronics’ decision to launch “lite” versions of its flagship PMICs reflects a broader industry shift toward cost‑conscious design, especially for devices that do not require the full suite of 14 power rails. By trimming unnecessary buck converters, LDOs, and boost stages, the company aligns its product portfolio with the growing segment of developers focused on volume‑driven, low‑margin applications.

The STPMIC1L and STPMIC2L retain core functionality—supporting 2.8 V to 5.5 V inputs and operating across –40 °C to 125 °C—while offering a smaller 4 mm × 4 mm and 5 mm × 5 mm footprint, respectively. Pricing at $1.34 and $1.77 per thousand‑unit lot represents a 21% to 50% reduction versus legacy parts, making integrated power management competitive with discrete buck and LDO solutions. This price elasticity is likely to persuade the 40% of STM32MP1 users who currently assemble separate components to adopt the integrated approach, reducing PCB complexity and time‑to‑market.

Targeted at point‑of‑sale terminals, barcode scanners, network gateways and industrial edge devices, the new PMICs position STMicroelectronics to capture a larger share of the burgeoning IoT and edge‑compute market. Competitors will need to respond with similarly streamlined offerings or risk losing design wins to cost‑sensitive OEMs. As the ecosystem embraces more compact, battery‑powered and USB‑powered devices, the balance between integration depth and price will become a decisive factor in component selection, and ST’s “L” series could set a new benchmark for affordable power management.
