BL8027
BL8027 is 1.5A 1.5MHz Synchronous Buck Converter manufactured by BELLING.
1.5A 1.5MHz Synchronous Buck Converter
DESCRIPTION
The BL8027 is a high-efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. The device is available in an adjustable version. Supply current with no load is 40u A and drops to <1u A in shutdown. The 2.5V to 6V input voltage range makes the BL8027 ideally suited for single Li-Ion battery powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. PWM/PFM mode operation provides very low output ripple voltage for noise sensitive applications.
Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors. Low output voltages are easily supported with the 0.6V feedback reference voltage.
The BL8027 is available in SOT23-5 package.
