|
The FP5003, a high performance monolithic IC, includes adjustable frequency oscillator and error amplifier for pulse modulation width (PWM) control, 1.0V precision voltage reference, under-voltage lockout circuit (UVLO), variable pulse width dead time control (DTC) circuit and programmable auto-restart timer for short circuit shutdown protection (SCSAR). Built-in totem-pole transistors pair to drive MOS directly at high frequency operation for high efficiency. It is very easy to design a dc-dc converter using a few external components, and typical application example is shown below. |
