The BP5311A from ROHM Semiconductor is a DC/DC converter specifically designed for supplying power to liquid crystal display (LCD) panels. It takes a standard +5V logic circuit power supply and outputs a positive voltage suitable for LCDs. This module is available in a compact, lightweight 9-SIP, 7-lead package and features through-hole mounting.
Key features include high conversion efficiency, reaching up to 77%, and a built-in ON/OFF switch for control. The device operates within a 0°C to 60°C temperature range and has an input voltage range of 4.5V to 5.5V, with a typical input of 5V. The output voltage is typically 29.5V, with a maximum output current of 25mA. It also includes a built-in protection circuit.
Applications for the BP5311A include LCD panels in personal computers and word processors. Its design allows for surface mounting due to parts being concentrated on one side, although this specific model is a through-hole type. The module offers a typical output voltage of 29.5V and is suitable for applications requiring a stable positive voltage for LCD displays.

The input voltage range is 4.5V to 5.5V, with a nominal value of 5.0V at Ta=25°C and VCTL=5V with R1~R2 resistors disconnected.
The output voltage is typically 29.5V, with a range of 28V to 31V at VIN=5V and IOUT=20mA.
The BP5311A is available in a 9-SIP, 7-lead through-hole package.
The operating temperature range is 0°C to 60°C.
Typical efficiency is 77%, with a minimum of 67% under specified conditions.
The ripple noise voltage is typically 100mVp-p, maximum 200mVp-p.
The ON/OFF control pin requires a voltage of at least 1.5V to enable the output and a maximum of 0.5V to disable it. The control current is typically 500µA when VCTL=0V.
