Product Overview
NCP1239LD100R2G is a fixed-frequency current‐mode controller for a flyback converter. This fixed-frequency current-mode controller features a high-voltage start-up current source to provide a quick and lossless power-on sequence. This function greatly simplifies the design of the auxiliary supply and the VCC capacitor by activating the internal start-up current source to supply the controller during start-up, transients, latch, stand-by, etc. With a supply range upto 35V, the controller hosts a jittered 100KHz switching circuitry operated in peak current mode control. When the power on the secondary side starts to decrease, the controller automatically folds back its switching frequency down to a minimum level of 26KHz. It is used in applications such as AC-DC converters for TVs, set-top boxes and printers, offline adapters for notebooks and netbooks.
- Adjustable over power protection circuit, high-voltage current source with brown-out detection
- Internal slope compensation, internal fixed soft-start, pre-short ready for latched OCP versions
- Frequency jittering in normal and frequency foldback modes, extremely low no-load standby power
- 64ms timer-based short-circuit protection with auto-recovery or latched operation
- Latched OVP/OTP input for improved robustness, 35V VCC operation
- ±500mA peak source/sink drive capability, internal thermal shutdown
- 128 OCP timer, 25.5V Vcc OVP threshold, latch Vcc OVP protection
- Latch fault pin protection, 68ms BO timer, 4ms soft start time
- Disable DSS function, peak source current is 500mA typical at (DRV high state, VDRV = 0V)
- Storage temperature range from -60°C to 150°C, 7-lead SOIC package
