Beschreibung
The EV37F82A is intended to act as a reference design for the MCP1012, implementing a complete design with secondary Microcontroller. The MCP1012 15W Reference Design demonstrates the ability of the MCP1012 (located on the primary side) to start up a 15W AC-DC Flyback Converter and then have it commanded by a microcontroller (located on the secondary side). Two key components enable the startup and secondary side regulation of an isolated power supply, the Microchip MCP1012 and the Microchip patented integrated magnetic winding transformer built by Würth Elektronik (pn: 750318659).
Eigenschaften
- MCP1012 uses an open-loop, constant off-time, peak current-mode current regulator.
- MCP1012 uses a high voltage silicon process (0.5µ 5v/30v/700v) to develop a High Voltage (HV) Linear Regulator. The HV Linear Regulator will be rated for 700V, with an input at VIN and a regulated bias output at VDD.
- VDD is monitored by an Under-voltage Lockout (UVLO) feature
- VDD is monitored by an Over-voltage Lockout (OVLO) feature
- The device’s internal open-loop, peak current-mode current regulator operates in constant Off-Time mode. The duration of the Off-Time is internally fixed at 20µs typical
- MCP1012 provides a MOSFET Gate Driver (GATE)
- The Gate Driver can be commanded either by the internal open-loop, constant off-time peak current-mode current regulator circuitry or by an external PWM command via PULSE
