TPS54356PWP

Синхронный понижающий импульсный стабилизатор, фиксированный, 4.5В-20В (Vin), 3.3В и 3А, HTSSOP-16.

The TPS54356PWP is a SWIFT™ step-down PWM synchronous buck Converter with an integrated high side MOSFET and a gate driver for an optional low side external MOSFET. Features include a high performance voltage error amplifier that enables maximum performance under transient conditions. The TPS5435x has an under-voltage-lockout circuit to prevent start-up until the input voltage reaches a preset value, an internal slow-start circuit to limit in-rush currents and a power good output to indicate valid output conditions. The synchronization feature is configurable as either an input or an output for easy 180° out of phase synchronization. The undervoltage lockout (UVLO) system has an internal voltage divider from VIN to AGND. The defaults for the start/stop values are labelled VIN. The internal UVLO threshold can be overridden by placing an external resistor divider from VIN to ground.
