KA3511 Overview
The KA3511/D is a fixed-frequency improvedperformance pulse-width modulation control circuit with plete housekeeping circuitry for use in the secondary side of SMPS (Switched mode power supply). It contains various functions, which are precision voltage reference, over voltage protection, under voltage protection, remote on/off control, power good signal generator and etc. OVP (Over voltage protection) section It...
KA3511 Key Features
- plete PWM control and house keeping Remote on/off section is used to control SMPS circuitry externally. If a high signal
- Few external ponents secondary outputs are grounded. The remote on/off
- Precision voltage reference trimmed to 2% signal is transferred with some on-delay and off-delay time of 8ms, 24ms respe
- Dual output for push-pull operation
- Precision reference section The reference voltage trimmed to ± 2% (4.9V≤Vref≤5.1V) PG (Power good signal generator) sect
- Each output TR for 200mA sink current Variable duty cycle by dead time control Soft start capability by using dead time
