| FP5452 DUAL PWM CONTROL IC WITH SCP/DTC FUNCTION | |||
|
General Description |
Download | ||
| The FP5452, a 1-chip composed of totem-pole output stage pulse-width-modulation control circuits with two error amplifiers and dead-time comparators (DTC), the FP5452 contains a 2.5V precision voltage reference regulator, under-voltage lockout circuit (UVLO), short circuit protection circuit (SCP), applied to offer space and low cost in many applications such as the DC/DC converter and backlight inverter. Using few external components, FP5452, a high performance integrated IC, is designed for a control circuit. The circuit diagram of the typical application example is as below. |
