CS5111
1.
4 A Switching
Regulator with 5.
0 V, 100 mA Linear
Regulator with Watchdog, RESET and ENABLE
The CS5111 is a dual output power supply integrated circuit.
It contains a 5.
0 V ± 2%, 100 mA linear
regulator, a watchdog timer, a linear output voltage monitor to provide a Power On Reset (POR) and a 1.
4 A current mode PWM switching
regulator.
The 5.
0 V linear
regulator is comprised of an error amplifier, reference, and supervisory functions.
It has low internal supply current consumption and provides 1.
2 V (typical) dropout voltage at maximum load current.
The watchdog timer circuitry monitors an input signal (WDI) from the microprocessor.
It responds to the falling edge of this watchdog ...
