Hw133v10 - Datasheet

Product Review: HW133V10 13.3" FHD LCD Display Module

Product: HW133V10 (13.3-inch TFT LCD Module) Manufacturer: Hengxuan (OEM/ODM available) Category: Industrial/Consumer Display Components

• No typical application schematic.
• Missing power consumption data for different refresh rates.
• Register map is incomplete (several reserved bits unexplained).

Possible explanations:

1. High-Side MOSFET Switch – Internal RDS(on) ≈ 150 mΩ
2. PWM Control Logic – Voltage mode control with feedforward
3. Error Amplifier – Transconductance type, 80 dB gain
4. 1.25V Bandgap Reference – Temperature compensated (±1%)
5. Oscillator – Fixed frequency (150 kHz ±10%)
6. Current Limiting Comparator – Cycle-by-cycle peak current limit (4.5A typical)
7. Thermal Shutdown – Triggers at 160°C, 20°C hysteresis
8. Under-Voltage Lockout (UVLO) – 6.5V turn-on, 5.5V turn-off

• The exact logic voltage thresholds.
• The initialization sequence for the V10 revision.

Part 1: Device Overview and Naming Convention

1.1 What is the HW133V10?

The HW133V10 is typically a fixed-output voltage regulator or a switching controller IC capable of handling high input voltages. The "HW" prefix often denotes a series from manufacturers like Huawei’s component division, Infineon, or a generic Asian semiconductor brand. The "V10" suffix strongly implies a 10-volt output or a 10-amp rating. Product Review: HW133V10 13
