Max767ca

The MAX767CA (part of the MAX767 series) is a high-efficiency, synchronous step-down (buck) controller primarily designed for 5V to 3.3V DC-DC conversion Analog. While highly efficient, this product series is currently obsolete and no longer in active production by its manufacturer, Analog Devices (formerly Maxim Integrated) Analog.

1. Product Specifications & Technical Role

The MAX767CA is optimized for converting a 5V system rail into a tightly regulated 3.3V output for microprocessors and high-speed logic Analog.

* Performance: Achieves >90% efficiency using synchronous rectification and a BiCMOS current-mode PWM control Analog.

* Scalability: Capable of output currents ranging from 1.5A to over 10A, depending on external N-channel MOSFETs Analog.

* Features: Selectable 200kHz/300kHz oscillator frequency and "Idle-Mode" for high efficiency during light loads Analog.

2. Market Trends & Availability

Because the part is discontinued, the market has shifted from direct manufacturing to secondary distribution and legacy support:

* Availability: Current stock consists primarily of "New Old Stock" (NOS) held by independent distributors Ebay.

* Sourcing Hubs: Verified distributors in Shenzhen, such as Shenzhen Sinosky Electronics and Seven Chips Electronics, maintain inventories of these legacy ICs to support maintenance and repair for older industrial and computing hardware AlibabaAlibaba.

* Price Dynamics: Prices for obsolete components can be volatile, often ranging from $0.10 to $5.00+ per unit depending on quantity, certification status (e.g., lead-free "CAP+" vs. original), and remaining global supply .

3. Strategic Recommendations

For businesses managing systems that utilize the MAX767CA:

* Maintenance: Secure batches of MAX767CAP+ (the lead-free version) from verified suppliers who can provide a Certificate of Conformance (CoC) to ensure part authenticity MouserAlibaba.

* Redesign: For new development, transition to modern alternatives like the MAX797 or newer integrated switching regulators that offer smaller footprints and higher thermal performance Analog.
