: The high-voltage DC feeds into a flyback transformer controlled by an integrated pulse-width modulation (PWM) switching chip.

Before the system can transition into an active power state (S0), the Power Management Integrated Circuit (PMIC) must establish low-current "Always-On" voltage rails:

To help find the exact variant you need, could you share the of the portable device? If you are facing a specific hardware issue, please describe the symptoms so we can look up targeted diagnostic steps. Share public link

If you cannot find the official schematic, you can reverse-engineer your own using:

When no schematic is available, a methodical approach is your best tool. You need to the board's critical sections:

Let’s analyze the typical circuit blocks you will encounter in the . Understanding these will make your repair work faster. : The high-voltage DC feeds into a flyback

The electrical entry point handles incoming raw voltage (typically 220V–240V AC). The schematic exhibits a safety topology consisting of input fuses, metal oxide varistors (MOVs) for surge suppression, and an electromagnetic interference (EMI) filter network designed to trap clean alternating current and filter grid spikes. 2. DC Voltage Conversion (The Low-Side)

The schematic illustrates how the charging IC communicates with the battery management system via the SMBus or I2C protocol to monitor cell voltage and temperature. 2. The Step-Down (Buck) Regulators

Fast recovery or Schottky diodes (e.g., SR360 or SR540) convert the high-frequency secondary pulses back into DC.

If you are seeking physical diagnostic materials or part catalogs, resources like the Haier Service Portal host indexed technical documentation, service manuals, and wiring layouts for verified HVAC personnel. If you are ready to troubleshoot, let me know:

Check output capacitor. You see 0V. Your portable schematic reminds you: “U2 (AMS1117) – Input must be >4.5V.” Input is fine, output is dead. Replace U2.
