在现代电子设备中,电源管理方案至关重要。特别是在低功耗、宽电压输入范围内,如何高效、稳定地升压并提供恒定的输出电压,是许多设计者面临的挑战。SLB628系列升压电源模块,凭借其出色的性能和灵活的输出电压配置,成为了低电压输入升压应用的理想选择。
GENERAL DESCRIPTION
The SLB628 is a constant frequency, 6-pin SOT23
current mode step-up converter intended for small,
low power applications. The SLB628 switches at
1.2MHz and allows the use of tiny, low cost
capacitors and inductors 2mm or less in height.
Internal soft-start results in small inrush current and
extends battery life.
The SLB628 features automatic shifting to pulse
frequency modulation mode at light loads. The
SLB628 includes under-voltage lockout, current
limiting, and thermal overload protection to prevent
damage in the event of an output overload. The
SLB628 is available in a small 6-pin SOT-23
package.
