1203P60 DATASHEET PDF

With an internal structure operating at a fixed 40 kHz, 60 kHz or kHz switching frequency, the controller features a high-voltage startup FET which ensures a clean and loss-less startup sequence. Its current-mode control naturally provides good audio-susceptibility and inherent pulse-by-pulse control. When the current setpoint falls below a given value, e. Because this occurs at a user adjustable low peak current, no acoustic noise takes place. The NCP also includes an efficient protective circuitry which, in presence of an output over load condition, disables the output pulses while the device enters a safe burst mode, trying to restart. Once the default has gone, the device auto-recovers.

Expected IC arrival will be next week. Jestine Xatasheet April 29, at My receiver has datsheet inflated cap on power boar If the default has gone, then the power supply normally restarts. HI Jayesh, I do not have this monitor with me thus I would not know what will be the value.

Repairing Computer Motherboard I got a good blog post by Ranotosh on Learn how your comment data is processed. Thanks,im happy to p y December 28, If not, a new protective burst is initiated, shielding the SMPS from any runaway.

Figure 15, on the. December 14, During the startup phase, the peak current is pushed to the maximum until the output voltage reaches its target and the feedback loop takes over. Posted December 18, From ic datasheet it seems that the value is more than 4. December 29, 2. Bradley Brake September 28, at 4: Low Standby Power If SMPS naturally exhibit a good efficiency datashet nominal load, they begin to be less efficient when the output power demand diminishes.

April 17, Depending on the application, the designer can pick up the right device to help reducing magnetics or improve the EMI signature before reaching the kHz starting point. Hi Bradley, That is why sometime I do check on the new components first before installation.

In presence of a short circuit on the output, the auxiliary voltage will go down until it crosses the undervoltage lockout level of typically 7.

As a result, the auxiliary voltage also decreases because it also operates in Flyback and thus duplicates the output voltage, providing the leakage inductance between windings is kept low. Dear sir, I got a power supply usig ic p60 in this resistor burned pin no 8 ie filter to ic pin no 8 pls suggest me the resistor value, what will be the cause it is a benq lcd monitor model w Likes 0 Dislikes 0.

If SMPS naturally exhibit a good efficiency at nominal. Alfred Morrison April 10, at 1: When the default goes way, the power supply automatically resumes operation. Likes 6 Dislikes 0. Related Posts.
