Mingjiada Supply ADI LTC3769 Series High Performance Synchronous Boost Converter Controller

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of the LTC3769, a 60V, low IQ, synchronous boost controller from ADI (Analog Devices). This device is designed for automotive, industrial, communications and battery-powered applications that demand wide input voltage ranges, low standby power consumption and high-efficiency boost conversion, providing customers with highly reliable power control solutions. Mingjiada Electronics offers genuine stock, sample procurement and BOM fulfilment services to help customers accelerate product selection and mass production implementation.

[ADI/LINEAR] LTC3769 — 60V, low IQ, synchronous boost controller
The LTC3769 is a high-performance, single-output, synchronous boost converter controller designed to drive all-N-channel power MOSFETs. Its synchronous rectification enhances efficiency, reduces power losses and lowers thermal requirements, thereby simplifying high-power boost applications. A no-load quiescent current of 28 μA extends the operating time of battery-powered systems.
The 4.5V to 60V input supply range accommodates a wide variety of system architectures and battery chemistries. When biased from the boost converter’s output or another auxiliary power supply, the LTC3769 can operate from an input supply as low as 2.3V after start-up. The device’s operating frequency can be set within a range of 50 kHz to 900 kHz, or it can be synchronised to an external clock via an internal PLL.

Key features of the LTC3769:
Synchronous operation for higher efficiency and reduced heat dissipation
Wide VIN range: 4.5 V to 60 V (absolute maximum 65 V); operating voltage as low as 2.3 V after start-up
Output voltage up to 60 V
±1% 1.200 V reference voltage
RSENSE or inductor DCR current sensing
100% duty cycle capability for synchronous MOSFETs
Low quiescent current: 28 μA
