AX3833-2.6A,18V,500KHz Synchronous Regulator停产


AX3833-2.6A,18V,500KHz Synchronous Buck Regulator DataSheet (2015年7月停产)

GENERAL 
    The AX3833 is a high efficiency 500 kHz synchronous step-down DC-DC converter capable of delivering 2.6A current. The AX3833 operates over a wide input voltage range from 4.5V to 18V and integrates 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 500 kHz switching frequency. It adopts the instant PWM architecture to achieve fast transient responses for high step down applications.

FEATURES
- Low R DS(ON)for internal switches (top/bottom) for internal switches (top/bottom) : 80mΩ/40 mΩ
- 4.5 -18V input voltage range
- 2.6 A output current capability
- 500 kHz switching frequency
- Instant PWM architecture to achieve fast transient responses.
- Cycle-by -cycle peak current limitation
- Internal softstart limits the inrush current
- ±1.5% 0.6V reference
- TSOT-23 -6L package

Applications
- Set Top Box
- Portable TV
- Access Point Router
- DSL Modem
- LCD TV
