Description

The GW4230 is a single-chip Maximum Power Point Tracking (MPPT) SoC designed for solar PV systems. Optimized for applications utilizing solar photovoltaic (PV) cells, the GW4230 achieves up to 99.9% MPPT efficiency (input efficiency without loss) and 99.3% conversion efficiency (output efficiency with loss) through a custom MPPT algorithm. It can also be configured for customer-specific tasks.

Typical Applications

  • MPPT solution for solar PV system
  • Energy harvesting
  • Any DC sources with MPPT behavior
  • USB battery charger
