Current Mode PWM
Converter for Low Voltage
Outputs
The NCP1595/NCP1595A is a current mode PWM buck converter
with integrated power switch and synchronous rectifier. It can provide
up to 1.5 A output current with high conversion efficiency. High
frequency PWM control scheme can provide a low output ripple noise.
Thus, it allows the usage of small size passive components to reduce
the board space. In a low load condition, the controller will
automatically change to PFM mode for provides a higher efficiency at
low load. Additionally, the device includes softstart, thermal
shutdown with hysteresis, cyclebycycle current limit, and short
circuit protection. This device is available in compact 3x3 DFN
package.
