BL8032G 500KHz, 18V, 2A Synchronous Step-Down Converter DESCRIPTION FEATURES • • • • • • • The BL8032G is a fully integrated, high-efficiency 2A synchronous rectified step-down converter. The BL8032G 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 BL8032G requires a minimum number of readily available standard external components and is available in a 6-pin SOT23 ROHS compliant package. High efficiency: up to 96% 500KHz frequency operation 2A output current No schottky diode required 4.5V to 18V 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 Thermal shutdown Inrush current limit and soft start Available in SOT23-6 -40°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 VIN C3 VIN 0.1uF 0.1uF L C1 Ren 22uF 100k VIN EN BST SW BL8032G GND L 4.7uH R3 FB 10k 3.3V/2A VOUT R1 C1 Ren 22uF 100k VIN EN 47k BST R2 SW GND 3.3V/2A VOUT R1 BL8032G C2 22uF 4.7uH 312k C2 FB R2 22uF 100k 15k Figure 1. Figure 2. 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. 3) C3 can be valued as 1uF, 0.1uF. www.belling.com.cn 1 PDF
