BL8033 500KHz, 16V, 3A Synchronous Step-Down Converter DESCRIPTION FEATURES        The BL8033 is a fully integrated, high-efficiency 3A synchronous rectified step-down converter. The BL8033 operates at high efficiency over a wide output current load range. This device offers two operation modes, PWM control and PFM Mode switching control, which allows a high efficiency over the wider range of the load.        The BL8033 requires a minimum number of readily available standard external components and is available in SOT23-6 package. High efficiency: up to 96% 500KHz frequency operation Up to 3A output current No schottky diode required 4.5V to 16V input voltage range 0.8V reference Slope compensated current mode control for excellent line and load transient response Integrated internal compensation Stable with low ESR ceramic output capacitors Over current protection with hiccup-mode Over temperature protection Inrush current limit and soft start Available in SOT23-6 -30°C to +85°C temperature range APPLICATIONS      Distributed power systems Digital set top boxes Flat panel television and monitors Wireless and DSL modems Notebook computer TYPICAL APPLICATION C3 C3 VIN VIN 1uF 1uF L L C1 Ren 22uF 100k VIN BST 4.7uH SW LC2333 BL8033 EN GND R3 FB 10k 3.3V/3A VOUT R1 C1 Ren 22uF 100k VIN EN 40.2k BST R2 SW GND 3.3V/3A VOUT R1 BL8033 LC2332 LC2333 C2 22uF 4.7uH 300k C2 FB R2 96k 13k Figure 2. Figure 1. Note: 1) C1 and C2 recommended using 22uF ceramic capacitors. If the electrolytic capacitor is used, it is recommended that the ceramic capacitor in parallel with a capacitance value of 0.1uF or more. 2) The resistance R3 in Figure 1 makes the loop more stable. If it isn’t used, the resistance R1、R2 should be adjusted(See Figure2.). The value of R1 is recommended to be about 300kΩ. www.belling.com.cn 1 22uF  PDF
