MPX2001 - All-in-One Flyback Controller

General Description

The MPX2001 is an all-in-one flyback controller solution.

The MPX2001 integrates a primary driving circuit, secondary controller, and synchronous rectification driver all in one chip, maintaining the benefits of both primary-side regulation (PSR) and secondary-side regulation (SSR).

Key Features

  • advanced protections, including primary-sense output over-voltage protection (OVP), primary over-current protection (POCP), real secondary-sense output overload protection (OLP), internal/external brown-in/brown-out (B/O, B/I), short-circuit protection (SCP), current-sensing short protection (SSP), internal thermal shutdown, under-voltage lockout (UVLO), and an externally triggered protection (Ext. P). The MPX2001 is available in SOICW20 and SOICW20-19 packages. MPX2001 All-in-One Flyback Contro.

The Future of Analog IC Technology DESCRIPTION The MPX2001 is an all-in-one flyback controller solution. The MPX2001 integrates a primary driving circuit, secondary controller, and synchronous rectification driver all in one chip, maintaining the benefits of both primary-side regulation (PSR) and secondary-side regulation (SSR). With the MPX2001, system complexity can be reduced since no feedback circuit is needed. Therefore, the total BOM cost is reduced. At the same time, a synchronous rectifier (SR) can be matched perfectly with the driving signal of the primary-side MOSFET. With this feature, the SR can operate safely in continuous conduction mode (CCM), which helps increase overall efficiency and provides the design with more flexibility.
