SGM37310规格书详情
描述 Description
The SGM37310 is an asynchronous Boost WLED driver with high efficiency, low EMI and high output voltage. The Boost converter integrates a 40V, 1.5A internal FET which operates at 1.2MHz switching frequency. Its strong driving ability can drive single or multiple parallel LED strings, which can be used as LED driver for smart phone and tablet backlight.
The default LED current can be programmed by the external current-sense resistor RSET. By varying the duty cycle of the PWM signal applied to the CTRL pin, the internal reference voltage is adjusted, which ultimately adjusts the LED sink current. With full PWM duty cycle, the internal reference voltage VREF is 200mV (TYP). The SGM37310 is essentially a driver that adopts analog dimming control, and it will not produce audible noise on the output capacitor. The SGM37310 integrates ringing cancellation, and it can effectively reduce EMI noise in DCM mode. The SGM37310 provides excellent line regulation and load regulation, as well as excellent load transient response. The SGM37310 also features various protection functions such as open LED protection, OCP protection and thermal shutdown protection.
The SGM37310 is available in a Green TDFN-2×2-6L package. It operates over an ambient temperature range of -40℃ to +85℃.
