SGM41282C

70V, 2.5mA Precision Protection APD Bias

Dual-Gain Track/Hold Current Mirror

GENERAL DESCRIPTION

FEATURES

The SGM41282C integrates a Boost converter for

generating up to 70V regulated output, a 1×/8×

dual-gain current mirror with a track and hold output

buffer, which is unique to simplify the fiber module

circuit design due to the use of low resolution ADC.

● Input Voltage Range: 2.8V to 5.5V

● Wide Output Voltage Range from (V_IN+ 5V) to 70V

● 850kHz Switching Frequency

● 1:30 Output Voltage Programming

● Adjustable Over-Current Protection

● Internal 1×/8× Dual-Gain Current Mirror

● 2.5V Voltage Buffer for Full-Scale Output Current

● Less than 1μA Shutdown Current

The SGM41282C is available in a Green TQFN-3×3-16L

package.

● Full Chain Circuit: Bias-Mirror-Track/Hold

● Replacement of *15059/*3430+*3923

● Available in a Green TQFN-3×3-16L Package
