uP1589Q IC
Product Title: uP1589Q (Marking: TYZ / TYZ433) Dual Synchronous Step-Down Controller IC for 3.3V / 5V Laptop Standby Power (WQFN-20L 3x3)
Product Specifications:
- Part Number / Marking: uP1589Q (Top Marking Code: TYZ / TYZ433)
- Device Type: Dual Synchronous Step-Down (Buck) PWM Controller IC with Integrated LDOs
- Package / Case: WQFN-20L 3x3 (20-Pin Surface Mount with Exposed Thermal Pad)
- Input Voltage Range ($V_{IN}$): $5.5\text{V to }26\text{V DC}$ (Primary Adapter / Battery Power Rail)

Short Description: High-efficiency uPI Semiconductor uP1589Q (top marking: TYZ) dual synchronous step-down PWM controller IC in a 20-pin WQFN package. Specifically designed to control the $3.3\text{V}$ and $5\text{V}$ primary standby power rails (3VALW / 5VALW) on laptop motherboards and embedded logic systems. Integrates dual linear regulators (3.3V and 5V LDOs) to supply low-power system management and Embedded Controllers (EC) prior to main board startup. Essential replacement component for repairing dead laptop motherboards, missing $3.3\text{V}/5\text{V}$ standby rails, short-circuit power cuts, and power-on failure conditions.
