BD9275F

Description

BD9275F

The BD9275F is a silicon monolithic integrated circuit that functions primarily as a DC-AC inverter control IC. It is widely used in power management applications, such as controlling backlights in LCD/LED televisions and display panels.

• Control architecture: 1-channel control utilising a Push-Pull topology.
• Manufacturing process: Built using a 20V process.
• Drive frequency accuracy: Rated at 3.5% using an internal built-in CT capacitor.
• Packaging style: Available in a standard surface-mount SOP-16 package.
• Feedback mechanism: Features dedicated lamp current and voltage sense feedback control loop systems.
• Built-in safety features: Incorporates a FAIL function, a highly accurate timer latch current (±15%), and adjustable slow-start / latch timing controls.
• Standby efficiency: Equipped with a Standby (STB) pin that limits current draw to a typical value of 0μA in standby mode.

• Supply voltage V_CC: 20V
• Output pin voltage (N₁, N₂): 20V
• Operating temperature range T_opr: -40°C to +85°C
