SY8037C SY8037DCC SY8037 HI3 HI2 H121B QFN12 IC

The SY8037C SY8037DCC SY8037 HI3 HI2 H121B QFN12 IC  is a compact and reliable synchronous step-down (buck) Charging IC designed to deliver high current with outstanding efficiency. Built around an advanced PWM control system, it achieves fast transient response and maintains stable output even under dynamic load changes.

Its integrated high-side and low-side MOSFETs with low RDS(ON) minimize conduction losses, ensuring cool operation in confined circuit spaces. With an input voltage range of 2.5V to 6V, this IC is well-suited for notebook, tablet, and DC-DC converter designs requiring compact power solutions.
