STI8036 500mA LNB-Power Supply & Control Voltage Regulator

PublishTime：2021-11-19

Intended for analog and digital satellite receivers/sat-TV, sat-OC cards, the STI8036 is a monolithic voltage regulator and interface IC, packaged in ESOP8, specifically designed to provide the 14V/19V power supply with high efficiency and the 22kHz TONE signaling to the LNB down-converter in the antenna dish or to the multi-switch box. STI8036 consists of a BOOST converter and a low-noise linear regulator along with the circuitry required for TONE injection and pin controllable interface. The device makes the total LNB supply design simple, efficient and compact with low external component count.
The external modulation input (TONE pin) can accept a tome modulated DiSEqC command and transfer it symmetrically to the output to meet DiSEqC 1.x protocol.
FEATURES:
⚫High Efficiency: Up to 90%
⚫Low noise output to avoid sensitivity of Can Tuner and DISH’s LNA dropping down
⚫Noise 40mV@20MHz BWL
⚫Single chip solution on 650mVpp
⚫22kHz TONE with 10μs T-rise/T-fall for less Transferring noise
⚫LNB Voltages (2 levels: 14V and 19V) compatible with common standards, Push-pull output stage minimizes 14V → 19V and 19V → 14V output transition times
⚫External 22kHz TONE input
⚫Integrated DC/DC BOOST converter and high efficiency (typ. 87%) with integrated Power MOSFET
⚫1.0MHz Switch Frequency BOOST
⚫Integrated low Noise Linear Regulator
⚫5.0V, 3.3V, 2.5V, 1.8V logic compatible
⚫Internal Short, OCP, OTP protection
⚫ESOP8 package
