The uP1590 is a dual synchronous buck controller with 5V/3.3V 100mA LDOs for notebook system power supply solution. The uP1590 supports high efficiency, fast transient response and provides a combined POK signal. The ultrasonic mode maintains the switching frequency above audio frequency, which elim.
include over current protection, over/under voltage protection, power-up sequencing, POK output, and thermal shutdown. The uP1590 is available in the space saving package WQFN3x3-20L, specified from -40OC to 85OC. Applications Notebook and Subnotebook System Power Supplies 3-4 Cell Li-Ion Battery-Power Devices Dual Output Supplies for DSP, Memory, L.
