Texas Instruments TLV1805-Q1 | Demoboard PMP21953

Description

This reference design demonstrates a cost focused approach of an isolated power supplies with low current capability. The design consists of three designs of three different topologies. All three design options are based on a high voltage comparator TLV1805-Q1 which works as a free-running oscillator and a driver. All three are unregulated, and the ouptut voltage directly depends on the input voltage.

Features

• 3.3 V to 40 V Supply Range
• Low Quiescent Current: 135 μA
• High Peak Current Push-Pull Output
• Rail-to-Rail Inputs with Phase Reversal Protection
• Built-In Hysteresis: 14mV
• 250ns Propagation Delay
• Low Input Offset Voltage: 500 μV
