Controller IC Chip - MAX1902E MAX1902EA MAXI902 MAX19O2 chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0672)

The MAX1901/MAX1902/MAX1904 are buck-topology,step-down, switch-mode, power-supply controllers thatgenerate logic-supply voltages in battery-powered sys-tems. These high-performance, dual/triple-output devicesinclude on-board power-up sequencing, power-good sig-naling with delay, digital soft-start, secondary windingcontrol, low dropout circuitry, internal frequency-compen-sation networks, and automatic bootstrapping.Up to 97% efficiency is achieved through synchronousrectification and Maxim’s proprietary Idle Mode™ controlscheme. Efficiency is greater than 80% over a 1000:1load-current range, which extends battery life in systemsuspend or standby mode. Excellent dynamic responsecorrects output load transients within five clock cycles.Strong 1A on-board gate drivers ensure fast external N-channel MOSFET switching.These devices feature a logic-controlled and synchroniz-able, fixed-frequency, pulse-width modulation (PWM)operating mode. This reduces noise and RF interferencein sensitive mobile communications and pen-entry appli-cations. Asserting the SKIPpin enables fixed-frequencymode, for lowest noise under all load conditions.The MAX1901/MAX1902/MAX1904 include two PWM reg-ulators, adjustable from 2.5V to 5.5V with fixed 5.0V and3.3V modes. All these devices include secondary feed-back regulation, and the MAX1902 contains a 12V/120mAlinear regulator. The MAX1901/MAX1904 include a sec-ondary feedback input (SECFB), plus a control pin(STEER) that selects which PWM (3.3V or 5V) receives thesecondary feedback signal. SECFB provides a methodfor adjusting the secondary winding voltage regulationpoint with an external resistor divider, and is intended toaid in creating auxiliary voltages other than fixed 12V.
