Description
MAX1771ESA is a high-voltage PWM DC-DC converter controller from Maxim (now Analog Devices) geared for automotive and industrial power supplies. It typically drives an external MOSFET to form a buck (and in some configurations buck/boost) regulator. Key points:
- Wide input range suitable for automotive harsh environments (often up to ~60 V)
- Current-mode PWM control with soft-start
- Programmable switching frequency
- Protection features: undervoltage lockout, overcurrent/short-circuit protection, and thermal shutdown
- Enable/disable control and fault reporting
- ESA suffix denotes a specific packaging/temperature grade (e.g., automotive/industrial variant)
Use: design compact, efficient DC-DC converters with robust protection for harsh operating conditions. For exact electrical specs, pinout, and recommended application circuitry, consult the official MAX1771ESA datasheet.
