FP5003
High Frequency PWM Controller With Short Circuit Restart
General Description
The FP5003, 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:
Features
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)
