RTQ5132 Datasheet | Richtek

Description The RTQ5132 is an integrated power management IC designed for general DDR5 SODIMM and UDIMM applications. This device provides three Buck converters (SWA, SWB, and SWC) and two LDOs (VLDO_1.0V and VLDO_1.8V). Additionally, the RTQ5132 supports a selectable interface (I2C or I3C basic) to acmodate various application environments. A prehensive protection mechanism is embedded to ensure safe power distribution, with the capability to record fault events in registers and signal them through PWR_GOOD and GSI_n open-drain indicators. The RTQ5132 is available in a WQFN-28L 3x4 (FC) package. The remended junction temperature range is from - 10o C to 125o C and the ambient temperature range is from 0C to 85C. 2 Ordering Information - MTP Serial Number 0 = JEDEC Default Code Single or Dual Phase 1 = SWA/SWB Single Phase 2 = SWA/SWB Dual Phase Version Package Type(1) QWF: WQFN-28L 3x4 (FC) (W-Type) Lead Plating System G: Richtek Green Policy pliant(2) Note 1. - Marked with (1) indicated: patible with the current requirements of IPC/JEDEC J-STD-020. - Marked with (2) indicated: Richtek products are Richtek Green Policy pliant. 3 Marking Information For marking information, contact our sales representative directly or through a Richtek distributor located in your area. 4 Features - VIN_Bulk with Input Supply Range: 4.25V to 5.5V - High Integration: - Three High Efficiency Buck Converters - SWA: ITDC = 4A, IMAX = 5A - SWB: ITDC = 4A, IMAX = 5A - SWC: ITDC = 1A, IMAX = 2A - Two LDOs - VLDO_1.8V: IMAX = 25m A - VLDO_1.0V: IMAX = 20m A - 0.75% Converter Output Accuracy - Fast Transient Response with A2RCOT Control - Support I2C and I3C Slave Control - Error Log Counter and Data Storage (NVM) - MTP Registers with Secured R/W Access - Programmable and DIMM Specific Registers for Customization - Programmable Mode for Debug and Validation - Telemetry for Output Current, Voltage, and Power - plete Protection Mechanisms - VIN_Bulk Input Supply OVP - OVP, UVP, OCP,...
