PWM IC for the synchronized deflection system control
GENERAL DESCRIPTION
The M62501P/FP is a controller for a deflection system of CRT display monitors. It performs a stable PWM control over a wide fluctuation of external signals, thanks to the built-in trigger mode oscillator. The IC is suitable for an application to a high voltage drive of monitors because of its following circuits and functions; * low voltage mulfunction protection circuit, * over or under voltage protection circuit for a control line, * soft-start function. It is also applicable to a horizontal output correction.

C1 C1,C2 VR1 Stabilization capacitors of Vcc and VREF. It is decided considering a load capacity of VREF. (A load capacity is approximately 5mA.) Recommended value is around 10k. They are for the soft start function. A time constant is decided considering VR1. This capacitor is for stabilization of AGC. A larger capacitor improves a stability of the system, however a system response is degraded. Recommended value is around 1F. This capacitor is for a saw wave generation. Recommended value is around 1000pF. They are for a gain setting of the error Amp. R2 should be several k to dozens of k to set a voltage gain 20dB to 40 dB at f = 1kHz, so that the feed back loop is stable. When the voltage gain is too low, it causes jitter. Recommended values of C4, C5 and R1 are ; C4 = dozens of pF to several hundreds pF C5 = several thousands pF to tens of thousands pF R1 = dozens of k to several hundreds k.
