The CXSD6181, a high performance monolithic IC, includes adjustable frequency oscillator, error amplifier for pulse width modulation (PWM) control, 1.0V precision voltage reference, under-voltage lockout circuit (UVLO), variable pulse duty control (DTC) circuit and programmable auto-restart timer for short circuit shutdown protection (SCSAR). Built-in totem-pole transistors pair drives MOS directly at high frequency operation with high efficiency. It is very easy to design a DC-DC converter using a few external components. The typical application example is shown below:
˙ Wide Operating Voltage Range:3.6~30V
˙Reference Voltage Precision: ±2%
˙Output Source / Sink Current up to 100mA
˙Totem-Pole Output for MOS Drive
˙Oscillator Frequency:Max.1.5MHz
˙Variable Duty Control (DTC)
˙Under Voltage Lockout Protection Function (UVLO)
˙Short Circuit Shutdown Protection / Auto Re-start Function (SCSAR)
˙Package:SOP-8L / MSOP-8L / SOP-8L (EP)
