ST offers a broad portfolio of highly integrated voltage and current controllers (ICs) designed for constant voltage (CV) and constant current (CC) switch mode power supply (SMPS) applications. These ICs are ideal solutions for battery chargers, AC-DC adapters, and LED drivers. By integrating a precise voltage reference with multiple operational amplifiers, ST’s controllers help engineers build robust and safe SMPS designs with very low power dissipation and reduced electrical stress on secondary side components.
From compact SOT23 6L packages to high stability SO 8 options, ST’s controllers simplify control loop design, reduce external component count, and maintain excellent voltage and current regulation accuracy.

Benefits
- Dual-loop regulation: Seamless transition between constant voltage and constant current modes for optimal battery charging profiles.
- High accuracy: Internal voltage references with up to ±0.5% precision ensure stable output even across wide temperature ranges.
- Space & Cost savings: Integration of multiple components (reference + opamps) into a single small package (SOT23-6L or SO-8) reduces PCB footprint and BOM cost.
- Energy efficiency: Designed for low quiescent current and minimal external components, helping manufacturers meet global "Green Energy" and standby power standards.
