BL8532B
White LED PFM Step-Up DC-DC Converter
Outline:
The BL8532B is a PFM Step-up DC/DC
driver IC with invariant current, design for LED
applications. Thought the external resistance,
output current reach 0mA~500mA.
A low ripple, high efficiency step-up DC/DC
converter can be constructed of BL8532Bxx
with only three external components. Also
available is a CE (chip enable) function that
reduce power consumption
Features:
• Low start voltage:0.8V ( at Iout=1mA);
• Output Current range:0~ 500mA;
• Output Current accuracy:±10%;
• High Efficiency:82%(Type);
• PACKAGE: SOT-89-5.
Applications:
• Power source for white LED
• Supply constant current
• Power source for a single or dual-cell
battery-powered equipments
