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 benefit s 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 help s increase overall efficiency and provides the design with more flexibility. The MPX2001 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 a SOICW -20 package.

The maximum allowable continuous power dissipation at any ambient temperature is calculated by P D (MAX) = (T J (MAX)-TA)/θJA. Exceeding the maximum allowable power dissipation produces an excessive die temperature, causing the regulator to go into thermal shutdown. Int ernal thermal shutdown circuitry protects the device from permanent damage. 3) The device is not guaranteed to function outside of its operating conditions. 4) Measured on JESD51-7, 4-layer PCB.

OPERATION The MPX2001 is an all-in-one flyback controller that maintains all benefits of a secondary-side regulator ( SSRs), reducing system complexity and the total solution cost . The MPX2001 solution implements a complete secondary -side regulation scheme. Both the control loop and the modulation block are placed on the secondary side, so the driv e signal of the synchronous rectifier (SR) can be perfectly matched with the drive signal of the primary -side MOSFET. With this feature, the SR is able to operate safely in continuous conduction mode (CCM), which helps increase overall efficiency greatly and provide more flexibility to the design. PRIMARY IC FUNCTION SECTION Self-Configuration at Start-Up Once VCC is higher than the minimum operation voltage (VCC-MIN) (typically 8V), the primary IC starts to read the EBO configuration . This is done before entering any other operation. If EBO is c onnected to an external resistor divider (typically >1kΩ), the external brown-in/- out mode is selected. In this mode, the brown- in/-out function senses the input voltage through EBO instead of sensing it through HV internally. The brown-in/-out detection is always enabled , regardless of whether the HV current source is turned on or off. This mode provides a more accurate brown-in/-out approach and adjustable thresholds. If EBO is s horted to PGND t o disable the external sensing, the internal brown -in/-out mode is selected. In this mode , brown-in/-out relies on the inte rnal sensing through HV. Brown-in/-out detection turns off when the HV current source is turned on (to avoid the effect of the HV voltage drop) and is always turned back on after the HV current source is turned off. This self-configuration action is executed only once, and the results are latched as long as the primary IC is active. Start-Up with Brown-In/-Out Detection Initially, all primary IC operation is disabled when there is no power applied, and the brown-in/-out flag defaults in brown -out state. Th e VCC of primary IC (VCC) is charged up by the internal high-voltage current source drawn from HV. The current source is turned off once VCC reaches VCC-IOFF (typically 14.5V). If the device is configured with external brown- in/-out mode, brown-in/-out detection is enabled right after self -configuration. If the device is configured with brown -in/-out internal mode, brown-in/-out is only enabled after the HV current source is turned off. If the HV voltage is higher than V HV-ON (typically 106V), then this is treated as a brown-in condition. The primary IC turns on the HV current source to charge VCC back to VCC-IOFF (to guarantee a maximized start- up window) and operates in normal start -up mode. Otherwise, it is treated as a brown-out protection condition . The primary IC operation remains disabled until VCC drops down to V CC- AUT (typically 5.3V), and VCC is charged up by the high-voltage current source all over again. Once VCC is higher than the minimum operation voltage (VCC-MIN), the primary IC begins monitoring on the sync signal transmitted through the insulation channel. Before brown-in is detected and the primary IC runs into normal start-up mode, the primary IC can alr eady determine what status the secondary IC is in. As shown in Figure 2, there are three conditions for primary IC start-up. 1. If there is no logic high state detected for the sync signal, the primary IC indicates that either the secondary IC is out of power or the system is recovering from a fault state. In this case, when brown -in is detected and the primary IC runs in normal start-up mode, the primary IC starts switching on its own with the maximum switching freq uency and the maximum peak current. Once any logic-high state of the sync signal is detected, the primary IC stops independent switching, and the secondary IC takes control. There is also a time limit on the primary start -up period. Even if there is no log ic-high state detected for the sync signal, the independent primary switching stops when the timer (tOCP) times out. This means that there is a fault condition present, such as overload, which is preventing the secondary IC from powering up successfully. tOCP starts after the soft-start period. Once the primary

Short-Circuit Protection (SCP) If the CS voltage is over V SCP, the peak current is not well -controlled by the peak -current limitation due to a fault condition, such as winding short -circuit or output short -circuit. Short-circuit protection (SCP) is triggered as an auto-restart mode protection. A reduced LEB time (tLEB-S, typically 235ns) is also adopted by the SCP comparator. Over-Voltage Protection (OVP) If VCC is over VCC-OVP (typically 27V), it indicates that the output voltage is not under control, and a large output overshoot can occur. OVP is triggered as a result in an auto-restart mode. The primary OVP can avoid component breakdown caused by over-stress. Brown-Out Protection (BOP) For more information about brown-out protection, refer to the Start-Up with Brown -In/-Out Detection section on page 18 and the Brown-Out Protection during Normal Operation section on page 19. Brown-out protection (BOP) is an auto- restart mode protection. Primary Over-Temperature Protection (POTP) To prevent any thermal damage on the chip, primary over -temperature protection ( POTP) shuts down the switching immediately when the junction temperature is over T OTP (typically 150°C). The protection flag is latched until the junction temperature drops by T∆ (typically 40°C), and POTP enters auto-restart mode. Primary Over-Current Protection (POCP) For more information about primary over-current protection (POCP), refer to the Start -Up with Brown-In/-Out Detection section on page 18. If the primary side does not receive a start -up signal from the secondary side for tOCP (typically 69ms), primary over-current protection is triggered. POCP is an auto -restart mode protection. Open/Short Protection on CS (CSP) CS is pulled high internally by the line compensation current source. SCP is triggered if CS is open. Conversely, CSP can also be triggered if the duty-on time reaches ~10µs and the CS voltage is ~0V, or the IC indicates a short- circuit condition on the current -sensing resistor or an inappropriate transformer design . CSP is an auto-restart mode protection. Primary External Protection (PEP) PEP is a general-purpose protection pin. There is an internal current soured out of PEP with a fixed value of I PEP (typically 100µA) (see Figure 7). A resistor or a BJT can be connected to PEP to create the target voltage. When the PEP voltage is lower than the protection trigger threshold (VPEP-T, typically 0.5V) and the condition lasts longer than the trigger delay time (tPEP_T, typically 300µs), the sync signal is set to logic high by PEP. The PEP flag is not reset until VCC drops below VCC-AUT. 0.5V PEP Timer Ext.P Figure 7: Primary External Protection PEP also has a saturation voltage (VPEP-S, typically 1V). If the external resistor is high enough to make the PEP voltage reach the saturation value, the PEP current is no longer fixed, but determined by the external resistance. Due to this characteristic, the current consumption during normal operation can be limited at a very low level. Typically, PEP can be used to implement an OTP function for external power devices (e.g. : primary MOSFET) by connecting to a negative temperature coefficient (NTC) resistor. Response to the Secondary Protections For more information about responses to secondary protections, refer to the Start-Up with Brown-In/-Out Detection section on page 18.
