一,产品概述(General Description)
The CXSD61032 are high-efficiency 1.5MHz synchronous step-down DC-DC
regulator ICs capable of delivering up to 1.5A output currents, respectively. The
CXSD61032 operates over a wide input voltage range from 3V to 5.5V and integrate
main switch and synchronous switch with very low RDS(ON) to minimize the
conduction loss. Low output voltage ripple and small external inductor and
capacitor sizes are achieved with 1.5MHz switching frequency.
二.产品特点(Features)
low Rds(on) for internal switches (top/bottom):
3-5.5V input voltage range
1.5MHz switching frequency minimizes
the external components
Internal softstart limits the inrush current
100% dropout operation
Compact and thermally enhanced package:
SOP8-PP
三,应用范围 (Applications)
LCD TV WiFi
Card GPS
Access Point Router
Set Top Box
