Analog Devices LTM4709 | Demoboard EVAL-LTM4709-BZ
Single 9A, Ultralow Noise, High PSRR, Ultrafast μModule Linear Regulator with Configurable Output Array
Overview
| Topology | Other Topology |
| Input voltage | 0.6-5.5 V |
| Output 1 | 4.2 V / 9 A |
Description
The EVAL-LTM4709-BZ evaluation board features the LTM®4709, a triple 3A, ultralow noise, high power supply rejection ratio (PSRR), and ultrafast μModule® linear regulator with a configurable output array. The input voltage (VIN) ranges from 0.6V to 5.5V. There are jumpers to set a 3-bit trilevel code that determines the output voltage (VOUT) at preprogrammed levels that range from 0.5V to 4.2V. The maximum output current is 9A since the LTM4709 is configured as a single output. The EVAL-LTM4709-BZ requires an external BIAS voltage (VBIAS) at least 1.2V higher than VOUT and between 2.375V and 5.5V.
