The MAX1576 charge pump drives up to 8 white LEDs with regulated constant current for uniform intensity. The main group of LEDs (LED1-LED4) can be driven up to 30mA per LED for backlighting. The flash group of LEDs (LED5-LED8) are independently controlled and can be driven up to 100mA per LED (or 400mA total). By utilizing adaptive 1x/1.5x/2x charge-pump modes and very-low-dropout current regulators, the MAX1576 achieves high efficiency over the full 1-cell lithium-battery voltage range. The 1MHz fixed-frequency switching allows for tiny external components, and the regulation scheme is optimized to ensure low EMI and low input ripple.The MAX1576 uses two external resistors to set the main and flash full-scale (100%) LED currents. Four control pins are used for LED dimming by either serial control or 2-bit logic per group. ENM1 and ENM2 set the main LEDs to 10%, 30%, or 100% of full scale. ENF1 and ENF2 set the flash LEDs to 20%, 40%, or 100% of full scale. In addition, connect either pair of control pins together for single-wire, serial pulse dimming control.The MAX1576 is available in a 24-pin thin QFN, 4mm x 4mm package (0.8mm max height).

MAX1576ETG+ is an authentic electronic component manufactured by Analog Devices, categorized under Driver ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official MAX1576ETG+ datasheet above.
Electronic component spot-market pricing for MAX1576ETG+ fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for MAX1576ETG+ depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
