SY8008B Overview
Key Specifications
Package: LSSOP
Operating Voltage: 5 V
Length: 2.95 mm
Width: 1.6 mm
Description
The SY8008A, SY8008B and SY8008C are highefficiency 1.5MHz synchronous step-down DC-DC regulator ICs capable of delivering up to 1.2A output currents. The SY8008 family operate over a wide input voltage range from 2.5V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
Key Features
- low Rds(on) for internal switches (top/bottom) ο SY8008A: 300m Ω /250m Ω, 0.6A ο SY8008B: 250m Ω /200m Ω, 1A ο SY8008C: 200m Ω /150m Ω, 1.2A
- 2.5-5.5V input voltage range
- 1.5MHz switching frequency minimizes the external components
- Internal softstart limits the inrush current
- 100% dropout operation
