The ME3159 is a 180kHz, PWM mode constant voltage Buck DC-DC converter featuring a wide operating voltage range from 8V to 36V. It includes an integrated low on-resistance power MOSFET and built-in loop compensation circuitry to reduce the number of external components required. This manual is written in Chinese.
| Input Voltage Range | 8V to 36V |
|---|---|
| Maximum Output Current | 5A |
| Oscillator Frequency | 180KHz |
| Output Voltage Range | 1.25V to 33V |
| Minimum Drop-out Voltage | 0.3V |
| Thermal Shutdown Range | -40 to 150 C |
The oscillator frequency is 180KHz, which can drop to 50KHz during overcurrent protection.
The device is available in TO263-5 and TO252-5 packages.
The reference voltage at the FB pin is 1.25V, used to detect output voltage via a divider.
