Introduction
EG1182 is a 48V battery-powered step-down DC-DC power management IC with integrated voltage reference, oscillator, error amplifier, over-temperature protection, current limiting protection, and short-circuit protection, making it ideal for high-voltage 60V applications. When deployed in electric vehicle 48V controller systems, the EG1182 can directly replace LM317, LM7815, or resistive step-down linear regulators. With high efficiency and high reliability, it significantly reduces the overall controller temperature, enabling more reliable system operation.
Features
- Wide input voltage range: 20V to 60V
- Minimal external components, stable operation without external compensation network
- Protection features: overcurrent protection, short-circuit protection
- Single external capacitor for operating frequency setting (10KHz - 100KHz)
- UVLO undervoltage lockout:
- Vcc pin turn-on voltage: 6.5V
- Vcc pin turn-off voltage: 3.5V
- UVLO hysteresis voltage: 3V
- No external startup resistor required
- Built-in high-voltage power transistor with external high-voltage power transistor expansion for high output current applications
- Single external low-power resistor for peak current control
- Cycle-by-cycle current limiting
- Package options: DIP-8 and SO-8
Applications
- Electric motorcycle controllers
- Electric bicycle controllers
- High-voltage analog/digital industrial control systems
- Telecom 48V power systems
- Ethernet POE
- Portable mobile devices
- Inverter systems
