Description
Product details
The GG1172H is a high-performance primary-side regulation (PSR) dual-winding controller IC for lithium battery chargers, reducing system cost by eliminating the transformer's auxiliary winding and integrating a current sensing resistor. It supports constant current/voltage control and provides built-in BJT integration, making it ideal for isolated solutions under 25W. High-precision constant voltage via programmable modules for direct lithium battery charging. Built-in LED status indicator with an accurate color-switch current point. Primary-side current and voltage sensing that removes the need for a TL431, optocoupler, and auxiliary power supply. Built-in loop stability compensation .Comprehensive protections: VCC clamp/ under voltage , LED open/short circuit, FB resistor open/short circuit, output short circuit, and overtemperature protection. Integrated BJT suitable for isolated power designs up to 25W. |GG MICRO|GG MICRO DISTRIBUTOR IN INDIA|GG MICRO DISTRIBUTOR IN MUMBAI|GG MICRO DISTRIBUTOR NEAR ME|GG1172H|GG1172H RESELLER IN INDIA|GG1172H RESELLER IN MUMBAI|GG1172H RESELLER NEAR ME|
