Renesas Electronics ZL8802
The ZL8802 is a dual output or dual phase digital DC/DC controller. Each output can operate independently or be used together in a dual phase configuration for high current applications supporting 2-, 4-, 6-, and 8-phase operation with up to four ZL8802 controllers. The ZL8802 supports a wide range of output voltages (0.54V to 5.5V) operating from input voltages as low as 4.5V up to 14V.| Part No. | ZL8802 |
