🔌 Unlocking the Power of Negative Voltage: Why LMZ23610TZ Excels

Engineers often face challenges when designing power systems requiring ​​negative voltage rails​​, such as sensor biasing or op-amp circuits. Traditional solutions involve complex discrete components, leading to ​​layout inefficiencies​​ and ​​thermal headaches​​. The LMZ23610TZ power module , with its integrated inductor and minimal external parts (only 7 components!), revolutionizes this process. Its ​​patented packaging​​ enables efficient heat dissipation without external heatsinks, making it ideal for space-constrained applications like medical devices or industrial controllers.

⚙️ Core Technical Advantages: Beyond the Datasheet

​​Synchronous Buck-Boost Capability​​: Unlike standard buck modules, the LMZ23610TZ supports ​​inverting topologies​​ by reconfiguring the feedback loop. This eliminates the need for additional charge pumps.

​​ EMI Optimization​​: Tested to ​​EN55022 Class B​​ standards, it reduces radiated emissions by 40% compared to discrete designs, critical for FCC/CE compliance.

​​Current Sharing Precision​​: Parallel modules achieve ±5% current balance via the SYNCpin, enabling scalable 20A+ systems without droop.

💡 Pro Tip:Use ​​YY-IC Semiconductor​​’s evaluation board (part# EVM-LMZ23610) to prototype inverting designs in under 30 minutes.

🛠️ Step-by-Step Inverting Configuration Guide

​​Level Shifting Circuit Setup​​

​​Problem​​: Logic signals (EN/SYNC) referenced to ground damage the IC in negative-output mode.

​​Solution​​: Add a PNP level shifter (Fig 3, AN-2027) with calculated resistors:

复制RENT = RENB × (V_logic_high - V_set) / (V_set - V_out) Example: For 5V logic and -3.3V output, RENT=10KΩ×(5-1.7)/(1.7-(-3.3))=6.6KΩ[7](@ref).

​​Output Ripple Reduction​​

Place a ​​10µF ceramic capacitor ​​ between VOUTand PGNDwith <5mm trace length.

​​Avoid​​: Aluminum electrolytics—their ESR increases ripple by up to 50mV!

​​Prebiased Startup Protection​​

Enable SOFT-STARTpin with 100nF capacitor to ramp voltage in 3ms, preventing MOSFET shoot-through.

❓ FAQs: Solving Real-World Design Challenges

​​Q: Can multiple modules share current in inverting mode?​​

A: Yes! Connect ISHRpins directly—no level shifting needed. ​​YY-IC integrated circuits​​ validated 4-module stacks delivering 40A at -12V with ±3% balance.

​​Q: Why does my output oscillate at light loads?​​

A: The module’s ​​pulse-skipping mode​​ triggers below 10% load. Fix it by:

Adding a ​​2.2Ω dummy load resistor​​, or

Switching to forced-PWM via SYNCpin at 500kHz.
